Principles of Therapy
CVD development is closely related to lifestyle characteristics and
associated risk factors. There is overwhelming scientific evidence that
lifestyle modifications and reduction of risk factors can slow the development
of CVD both before and after the occurrence of a cardiovascular event.
Cardiovascular Disease Prevention
Primary prevention is aimed at the healthy population and those at
risk, such as individuals with one or more CV risk factors, who have not yet
experienced a CV event, while secondary prevention is instituted for those with
confirmed CVD or who have had a first index CV event (eg MI, stroke, or
transient ischemic attack). Prevention and treatment goals are intensified
based on the patient’s risk modifiers, 10-year CVD risk, lifetime CVD risk, and
the benefit of treatment, as well as comorbidities, frailty, and patient
preferences. Lifetime CVD risk can be estimated in apparently healthy
individuals, in patients with established ASCVD, and in people with type 2
diabetes mellitus with specific lifetime CVD risk scores, or it can be
approximated using factors such as age, level of risk factor, and risk
modifiers, etc.
Selection of Patients for Clinical Intervention
Early intervention is encouraged to address modifiable risk factors. For
high- to very high-risk patients, as well as those with established ASCVD
and/or DM, intensive lifestyle modification and appropriate drug treatment are
required. The risk profile of these patients should be monitored every 3–6
months. High-risk patients who are intolerant of statin therapy should be given
non-statin agents (eg Ezetimibe, monoclonal antibodies, bile acid sequestrants,
phytosterols). For low- to moderate-risk patients, treatment of risk factors is
generally not recommended. However, moderate-risk patients require monitoring
of their risk profile every 6–12 months, while low-risk patients may be given
conservative management that focuses on lifestyle interventions.
Pharmacological therapy
Cardiovascular Disease Prevention_Management 1
Antiplatelet Agents
Antiplatelet agents have been shown to reduce vascular mortality,
non-fatal reinfarction of the myocardium, non-fatal stroke in patients with
unstable angina (UA), AMI, stroke, TIAs or other evidence of CVD.
Aspirin
Primary Prevention
Low-dose Aspirin (75–100 mg/day) should not be routinely used for
primary prevention of ASCVD in patients >70 years old or in adults of any
age who have an increased risk of bleeding. However, it may be considered for
primary prevention of ASCVD in select patients aged 40–70 years with high ASCVD
risk but without bleeding risk, and in patients with DM at high or very high
CVD risk without contraindications. The risk-benefit profile should be assessed
before using Aspirin for primary prevention especially in patients with DM.
Aspirin is recommended for use in men >45 years, primarily to protect
against MI, and in women >55 years, primarily to protect against stroke.
Secondary
Prevention
Good
evidence shows that Aspirin therapy (75–100 mg/day) can prevent MI, stroke, and
CV death in both men and women with established CVD. A low dose or 75 mg/day is
recommended for individuals in the high-risk group or those with >20% risk
of MI and stroke, and in diabetic patients. Other groups recommend Aspirin in
all patients with established CVD (eg MI or revascularization), and in patients
without a history of CVD but with >10% 10-year CVD risk. Low-dose Aspirin
given indefinitely is recommended in patients with established CVD and after a TIA
or stroke, unless contraindicated. Long-term secondary prevention with Aspirin
and a second antithrombotic drug (a P2Y12 inhibitor or low-dose
Rivaroxaban) should be considered in patients whose risk for ischemic events is
high and risk for bleeding is low.
Clopidogrel
Clopidogrel
is recommended in combination with Aspirin for patients with UA/NSTEMI when
Ticagrelor or Prasugrel is unavailable or contraindicated. The recommended
dosing begins with an initial dose of 300 mg, followed by 75 mg daily for at
least 1 month and ideally up to 12 months. Clopidogrel is also recommended as
an alternative to Aspirin in patients who are intolerant to Aspirin and may be
considered in preference to Aspirin in those established ASCVD. It is also
recommended in patients with TIA or non-cardioembolic ischemic stroke.
Prasugrel
Prasugrel is recommended in combination with Aspirin only in P2Y12-inhibitor-naïve
patients (especially diabetics) in whom coronary anatomy is known and who will
undergo PCI. An initial dose of 60 mg is given at the time of PCI, followed by
10 mg daily for 12 months.
Ticagrelor
Ticagrelor
is recommended in combination with Aspirin in UA/NSTEMI/STEMI patients with
intermediate to high risk of ischemic events regardless of choice of therapy
(invasive or conservative). An initial dose of 180 mg is followed by 90 mg 12
hourly for 12 months.
Vorapaxar
Vorapaxar
is a protease activated receptor-1 (PAR-1) antagonist that inhibits platelet
activation. Studies showed that Vorapaxar, when given with other antiplatelet
agents, significantly reduced the incidences of MI, stroke, and death caused by
CVD.
Anticoagulants
For COVID-19 patients requiring oral anticoagulant therapy, drug-drug
interactions between oral anticoagulants and COVID-19 drugs as well as liver
and renal function should be considered in order to decrease the risk of
bleeding or thromboembolic complications.
Warfarin
Warfarin
may be used in post- MI patients for stroke prevention when clinically
indicated (such as atrial fibrillation or LV thrombus, dilated LV with poor
systolic function). It may also be considered for patients with paroxysmal or
chronic atrial fibrillation or atrial flutter. However, the combination of
Warfarin with either Aspirin or Clopidogrel increases the risk of bleeding and
should be monitored closely by checking the PT and international normalized
ratio (INR). The INR is monitored when using Warfarin.
Non-Vitamin
K Antagonist Oral Anticoagulants (NOACs)1
Novel
oral anticoagulants (NOACs), also called new oral anticoagulants or direct oral
anticoagulants, are direct-acting inhibitors of either thrombin (Dabigatran) or
factor Xa (Apixaban, Edoxaban, Rivaroxaban). They may be used in the prevention
and treatment of VTE, and in the prevention of stroke and systemic embolism in
patients with ACS and non-valvular atrial fibrillation.
Antihypertensive Agents2
The
initiation of drug therapy3 is recommended for patients with a BP of
≥130/80 mmHg and ≥10% estimated 10-year ASCVD risk, and those with a BP ≥140/90
mmHg and <10% estimated 10-year ASCVD risk. These agents include ACE
inhibitors, ARBs with calcium channel blockers, thiazide diuretics or beta
blockers, either alone or in combination. If the BP is uncontrolled despite
treatment with 3 antihypertensive medications at maximally tolerated doses, an
aldosterone antagonist, an alpha blocker, a centrally acting agent or a
vasodilator is considered.
Lipid-lowering Agents4
Lipid-lowering
agents include statins, fibrates, bile acid binding resins, Niacin, microsomal
transfer protein inhibitor (Lomitapide), PCSK9 monoclonal antibodies, selective
cholesterol-absorption inhibitor (Ezetimibe), as well as Evinacumab, Bempedoic
acid, Inclisiran, and Icosapent ethyl. These agents may halt the progression or
induce regression of coronary atherosclerosis. Statins are the drugs of choice
and have been shown not only to reduce hyperlipidemia but also to lower CV
events and mortality. A high-intensity statin is recommended to be given at the
highest tolerated dose to achieve the LDL-C goals specific to the patient’s
risk group. The use of statin therapy may benefit patients undergoing coronary
artery bypass grafting (CABG), preoperatively and postoperatively.
Statin
therapy recommendations per target LDL-C reductions as follows:
- High-intensity statin therapy (eg Atorvastatin
[40-80 mg], Rosuvastatin [20-40 mg]) for approximately ≥50% LDL-C reduction
- May be given to patients with ≥20% 10-year ASCVD risk
- Moderate-intensity statin therapy (eg
Atorvastatin [10-20 mg], Rosuvastatin [5-10 mg], Simvastatin [20-40 mg],
Pravastatin [40-80 mg], Lovastatin [40 mg], Fluvastatin [40 mg 12 hourly],
Pitavastatin [2-4 mg]) for goals of <50% lower LDL-C levels
- May be given to patients with 7.5-19.9% 10-year ASCVD risk
- Low-intensity statin therapy (eg Atorvastatin [5 mg], Rosuvastatin [2.5 mg], Simvastatin [5-10 mg], Pravastatin [10-20 mg], Lovastatin [20 mg], Fluvastatin [20-40 mg], Pitavastatin [1 mg]) for <30% reduced LDL-C levels
If
the LDL-C goals are not reached, it is recommended to combine a maximally
tolerated statin dose with Ezetimibe.

PCSK9
Monoclonal Antibodies
Example
drugs: Alirocumab, Evolocumab
PCSK9
monoclonal antibodies are indicated for the prevention of CV events. Alirocumab
reduces the risk of MI, stroke, and UA requiring hospitalization in patients
with established CVD, while Evolocumab reduces the risk of MI, stroke,
peripheral arterial disease, and coronary revascularization in patients with
established ASCVD. These agents are recommended in patients with FH who are
intolerant of statins, or for very high-risk FH patients whose treatment with a
maximally tolerated statin dose plus Ezetimibe did not achieve the target LDL-C
goal. As human monoclonal antibodies, PCSK9 inhibitors work by inhibiting the
binding of PCSK9 to low-density lipoprotein receptors (LDLRs), thus increasing
the number of available LDLRs to clear LDL thereby decreasing LDL-C
concentration. Alirocumab may be given as an adjunct to diet, alone or in
combination with other lipid-lowering therapies. Evolocumab may also be given
as an adjunct to diet and correction of other risk factors: In combination with
the maximum tolerated dose of a statin, with or without other lipid-lowering
therapies, or alone or in combination with other lipid-lowering therapies in
patients who are statin-intolerant or for whom statins are contraindicated.
Other Agents
Colchicine
at a low dose (0.5 mg/day) may be considered for the secondary prevention of
CVD, particularly if other risk factors are insufficiently controlled or if
recurrent CVD events occur despite optimal therapy. It has been shown to reduce
the risk of MI, stroke, coronary revascularization, and CV death in adult
patients with established atherosclerotic disease or with multiple risk factors
for CVD.
Vaccination
Patients
with CVD or other atherosclerotic vascular diseases (such as PAD, CAD), should have
an annual influenza vaccination. Some studies support the association between
pneumococcal pneumonia and the development of concurrent acute cardiac events
(eg MI, arrhythmia, new or worsening congestive heart failure), hence,
pneumococcal vaccination is recommended in high-risk populations. Influenza and
pneumococcal vaccinations are important for reducing the risk of respiratory
infections and subsequent complications in patients with CVD during the COVID-19
pandemic. Furthermore, all CVD patients are encouraged to receive the COVID-19
vaccination as the risk of severe COVID-19 infection is high.
Nonpharmacological
Patient Education
Counseling
should be part of the patient encounter as patients tend to respond more
favorably when engaged in the process. It is important to inform the patient
that multiple risk factors contribute to atherosclerosis which causes CVD;
therefore, the aim is to decrease the total risk from all these factors through
the maintenance of multiple healthy behaviors. If a goal related to a
particular risk factor cannot be reached, this can be addressed by achieving
greater reductions in other risk factors. Counseling regarding a healthy and
physically active lifestyle forms the foundation of primary prevention and has
the potential to either reduce or prevent the development of risk factors. It
would help to include family members in the educational process so they can
assist the patient in achieving lifestyle modifications. A plan is developed to
make the patient part of the management through shared decision making and
holding discussions over time so the patient is not overwhelmed by changing
several behaviors all at one time (eg smoking, diet, exercise). The approach to
care should be team-based, and social determinants of health should be
evaluated for ASCVD prevention. Patients should be re-educated about proper
food selection, stress management, self-monitoring, the importance of an active
lifestyle, and the maintenance of ideal body weight. Progress should be
monitored through follow-up contact, with regular re-evaluation and behavioral
interventions to maintain treatment adherence. As continuous medical management
is required for patients with CVD and its risk factors, patients are informed
about telehealth services, which may be used to ensure access to healthcare
providers during the coronavirus disease 2019 (COVID-19) pandemic.

Lifestyle Modification
Medical nutrition therapy, physical activity, and comprehensive lifestyle approaches have been shown to improve the control of modifiable risk factors and intermediate markers of CVD risk. Therapeutic lifestyle changes of proven benefit include diet modification, increased physical activity, weight loss, reduction or avoidance of alcohol, and smoking cessation.

Diet Modification1
The patient is counseled on a balanced diet consisting of fruits, vegetables, low-fat dairy products, fiber, whole grains, and protein sources that are low in trans-fat, saturated fat, and cholesterol. The total dietary intake of fats should be ≤30% of the total calories consumed, while the intake of saturated fats should be ≤7% of the total calories. Intake of polyunsaturated fats should be <10% of total calories, while monounsaturated fatty acids should account for <20% of caloric intake. Trans fats should be limited to <1% of total calories, and intake of dietary cholesterol should be <200 mg per day. Dietary options such as plant stanols or sterols at 2 g per day and soluble fiber at 30–45 g per day may be added. However, plant stanols or sterols are not advised in individuals being treated for primary or secondary prevention and those with CKD or type 1 or 2 DM. Saturated fats should be replaced with monounsaturated and polyunsaturated fats from vegetable or marine sources, as polyunsaturated fat has shown slightly greater LDL-C reductions compared to monounsaturated fat. A Mediterranean-style or plant-based diet rich in unsaturated fats lowers CV risk. Intake of beverages and foods with added sugar, red meat, and processed meat should be minimized.
The Prospective Urban Rural Epidemiology (PURE) study demonstrated that a high carbohydrate intake (>60% of total energy) was associated with adverse effects on total and non-CVD mortality, while a high fat intake, including both saturated and unsaturated fatty acids, was associated with a lower risk of total mortality, non-CVD mortality, and stroke. Therefore, overall carbohydrate intake should be limited, especially from refined sources; choose foods with low glycemic index or load. The recommended sodium intake for the general population is <5 g per day. Patients should be advised about the hidden salt content in processed foods. Consuming 30 g of unsalted nuts daily may help reduce CVD risk. Increasing the consumption (≥2 servings per week) of fish high in omega-3 fatty acids is also recommended. Daily intake of 2–4 g of fish oil can reduce triglycerides by ≥25%. AHA finds it reasonable to provide omega-3 polyunsaturated fatty acid supplementation for secondary prevention of CHD and sudden cardiac death in patients with prevalent CHD or heart failure. Food portions can be controlled by using a 9-inch plate, with half the plate composed of vegetables and fruits, and the other half divided between carbohydrates and proteins. Patients with CVD or identified risk factors such as diabetes, dyslipidemia, hypertension, or obesity may benefit from personalized dietary advice or referral to a dietitian.
1Dietary recommendations may vary between countries. Please refer to available nutritional guidelines from local health authorities.
Increased Physical Activity
Physical activity contributes to weight loss, glycemic control, improved BP, lipid profile, and insulin sensitivity. All individuals should be encouraged to engage in moderate-intensity aerobic activity, such as brisk walking, for at least 30 to 60 minutes per day, 5 to 7 days a week, or alternatively, 15 minutes per day for 5 days a week of high-intensity aerobic activity, such as jogging or swimming, or a combination of the two. This is done in addition to increasing daily lifestyle activities like household work, gardening, and walking breaks during work. Resistance training may also be advised at least 2 days a week. Patients with CVD or CVD equivalents should be assessed prior to beginning a vigorous physical activity for conditions that might contraindicate certain types of exercise or increase the risk of injury. Patients should be encouraged to exercise at their maximum safe capacity.
Moderate Alcohol Consumption
Alcohol consumption above 3 units per day increases BP, as well as the risk of cardiac arrhythmias, cardiomyopathy, and sudden death. Patients should be advised to abstain from alcohol or reduce their alcohol consumption. The goal is to limit alcohol intake to 100 grams per week, which corresponds to <2 glasses per day or 20 grams per day of alcohol for men, and one glass per day or 10 grams per day for women.
Smoking Cessation
Studies have shown that smoking accelerates coronary plaque development and may lead to plaque rupture, which is dangerous in patients with advanced coronary atherosclerosis. Smoking cessation has been shown to significantly increase HDL-C. Evidence supports its beneficial effect on CHD mortality. All smokers should be strongly encouraged by a health professional to quit smoking and be supported in their efforts to do so. This includes assessing the tobacco user’s willingness to quit, assisting through counseling and developing a quitting plan, and offering pharmacologic interventions (eg Nicotine replacement therapy, Bupropion or Varenicline) for motivated smokers who have failed to quit by counseling. However, the use of electronic cigarettes as a tool for smoking cessation is not recommended due to insufficient evidence and potential harm. Follow-up should be arranged, and referral to special programs is considered. It must be noted that successful smoking cessation program often requires a multidisciplinary approach. In addition, all non-smokers should be encouraged not to start smoking. The goal is complete smoking cessation and no exposure to environmental tobacco smoke.
Please see Smoking Cessation disease management chart for further information.
Weight Management
The risk of coronary disease and mortality is increased in obese patients, as obesity also contributes to other CHD risk factors (eg hypertension, dyslipidemia, type 2 DM). The presence of abdominal obesity particularly raises and independently predicts CV risk. Therefore, waist circumference along with the waist-to-hip ratio should be evaluated. The waist-to-hip ratio is indicative of central obesity. Gender-specific waist circumference cutoff points for increased CVD risk have been established in Asians, with values of ≥80 cm in women and ≥90 cm in men. Weight reduction results in lower BP, lower LDL-C and TG, higher HDL-C, and improvements in hyperinsulinemia and hyperglycemia, and is therefore recommended in overweight and obese patients. The initial target for weight loss is 5–10% for patients with a BMI of 20–25 kg/m². The goal BMI for Asian adults is 18.5–22.9 kg/m². Weight control can be achieved through a healthy diet maintained over time, increased physical activity, structured exercises, and behavioral counseling programs. Successful weight reduction requires sustained personal and family motivation, along with long-term professional support. Pharmacological intervention is also an option for patients who are determined to lose weight and will able to incorporate the therapy with comprehensive lifestyle intervention strategies.
Prevention
Management of Other Risk Factors
Blood Pressure (BP) Control
The goal is BP <140/90 mmHg in all patients, though BP targets
should be individualized. Recommendations for BP treatment goals may vary
between countries. Please refer to available guidelines from local health
authorities. The target SBP range is 130-139 mmHg in individuals ≥65 years old.
A DBP of <80 mmHg is recommended in all treated patients. BP goal and
management may be determined through risk stratification. BP should be recorded
at each visit. Lifestyle modification should be started in all patients,
including weight reduction, consumption of fruits, vegetables, and low-fat
dairy products, reducing salt intake, supplementing with dietary potassium
(3.5–5 g/day), limiting alcohol intake, and increasing physical activity. If BP
goals are not achieved with lifestyle changes alone, drug therapy is started
and individualized for each patient, considering age, race, or the need for
drugs with specific benefits, CVD risk, or the presence of
hypertension-mediated organ damage. Antihypertensive treatment is initiated in
patients with BP ≥130/80 mmHg who have established CVD or a 10-year ASCVD risk
>10%, and patients with BP ≥140/90 mmHg regardless of their CVD status or
calculated CV risk. Angiotensin-converting enzyme (ACE) inhibitors and
angiotensin receptor blockers (ARBs) as well as calcium channel blockers,
thiazide or thiazide-like diuretics and, for certain indications, beta-blockers
are commonly used in the treatment of CV disorders (eg hypertension, CAD, and
congestive heart failure. The risk of COVID-19 infection or of developing
severe complications from COVID-19 is not increased with prior or current
treatment with ACE inhibitors or ARBs; therefore, such treatment should be
continued as prescribed.
Please see Hypertension
disease management chart for further information.
Lipid Management
A reduction of plasma TC by 10% has been shown to decrease the
incidence of CAD by 25% after 5 years, while a reduction of LDL-C by 40 mg/dL
(1 mmol/L) is associated with a 20% reduction in CHD events.
Goal for LDL-C based on risk groups:
- Low risk: <116 mg/dL (<3 mmol/L)
- Moderate risk: <100 mg/dL (<2.6 mmol/L)
- High risk: <70 mg/dL (<1.8 mmol/L)
- Very high risk: <55 mg/dL (<1.4 mmol/L)
The
general lipid goals are:
- TC: <200 mg/dL (<5.18 mmol/L)
- HDL-C: As high as possible but at least >40 mg/dL (>1.0 mmol/L) in men and >45 mg/dL (>1.2 mmol/L) in women
- TG:
<150 mg/dL (<1.69 mmol/L)
- If TG is ≥200 mg/dL (≥2.26 mmol/L), non-HDL-C should be <130 mg/dL (<3.27 mmol/L) or <100 mg/dL (<2.59 mmol/L) for very high-risk individuals
- Apo B: <90 mg/dL in high-risk patients, <80 mg/dL in very high-risk patients with established ASCVD or DM with ≥1 additional risk factor, and <70 mg/dL in extreme-risk patients
Therapeutic lifestyle changes should be advised to all patients whose
lipid levels are above the goal range, and if levels are persistently above
treatment goals, a specialist referral should be considered. It is important to
stress the role of smoking cessation, weight reduction, and physical activity
in lipid management. Lipid-lowering therapy may be initiated. However,
secondary causes of dyslipidemia (such as hypothyroidism, alcohol abuse,
Cushing’s syndrome, diseases of the liver and kidneys) should be ruled out
before initiating treatment. Statins are commonly used for both primary and
secondary CVD events in high-risk patients. They are also the first drugs of
choice in high-patients with hypertriglyceridemia. Initiation of statin therapy
is recommended for patients aged 40–75 years with LDL-C levels between 70–189
mg/dL without clinical ASCVD or DM, patients ≥21 years of age with primary
LDL-C levels ≥190 mg/dL, and patients aged 40–75 years with DM. Statins may
also be considered for primary prevention in patients ≥70 years old if they are
at high risk or above. They are the first-line therapy for patients ≥75 years
old with clinical ASCVD unless contraindicated. It is important to discuss the
risks and benefits of statin therapy with the patient including possible
interactions with other drugs or substances. Although fibrates have not been
shown to reduce cardiovascular events, they may be used in the treatment of
severe hypertriglyceridemia. Individuals with TG >500 mg/dL should be
started with a fibrate in addition to statin to prevent acute pancreatitis.
Current evidence shows that lipid-lowering therapy is safe in patients with
COVID-19 infection, and such therapy should generally be continued in patients
with confirmed COVID-19 diagnosis and abnormal LFTs, unless alanine
transaminase (ALT) or aspartate transaminase (AST) levels progressively
increase, a significant drug-drug interaction between the lipid-lowering agents
and COVID-19 drugs has been identified, or the patient is critically ill and/or
unable to take oral medications. Bile acid sequestrants and Niacin may be
temporarily discontinued in patients with COVID-19 infection due to the lack of
evidence of CV outcome date.
Please see Dyslipidemia disease management chart for
further information.
Diabetes Management
Diabetic patients (type 1 or type 2) are at increased risk for CVD and
have worse outcomes after surviving a CVD event. Good glycemic control
substantially reduces the risk of CV events and microvascular diseases.
Therefore, treatment of DM is always recommended regardless of the overall risk
of vascular disease. Appropriate therapy is started to achieve near-normal
fasting plasma glucose levels (<7 mmol/L) or as indicated by near-normal
HbA1c levels, beginning with a healthy diet and regular exercise. The general
goal is an HbA1c <7% (<53 mmol/mol) for both type 1 and type 2 DM, but
since HbA1c may vary with the patient’s ethnicity or race, values must be
individualized. An HbA1c goal of ≤6.5% (≤48 mmol/mol) should be considered in
type 2 DM patients with good health status and without ASCVD.
To reduce the risk of hypoglycemia, glycemic targets should be
individualized based on the patient’s profile. Lifestyle modification, along
with BP and lipid management, is recommended in all diabetic patients. If
lifestyle modification fails, oral antidiabetic medications should be added to
the treatment regimen. Sodium-glucose linked transporter 2 (SGLT2) inhibitors
or glucagon-like peptide-1 (GLP-1) receptor agonists with proven CV benefit are
recommended for patients with type 2 diabetes mellitus (T2DM) and ASCVD to
reduce CV risk. Metformin should be considered if additional glucose control is
needed. Metformin should also be considered to reduce CV risk in T2DM patients
without ASCVD or severe TOD who are at low or moderate risk. Lipid-lowering
drugs are recommended for all patients with T2DM patients and for those with
type 1 DM >40 years old. These may also be considered in patients <40
years old who are at high risk with multiple risk factors and microvascular
complications, or who have had diabetes for ≤10 years. Patients with diabetes
require strict blood glucose monitoring and prevention of diabetes
complications during the COVID-19 pandemic in order to keep their
susceptibility low and to prevent severe COVID-19 disease courses.
Please see Diabetes Mellitus disease management chart
for further information.
Obesity/Overweight Management
Weight loss is indicated for patients with a WHO BMI >30 kg/m² or
25–29.9 kg/m² who have risk factors (DM, prediabetes, hypertension,
dyslipidemia, waistline >88 cm in women or >102 cm in men), or who have
obesity-associated comorbidities. The goal is to achieve a 5–10% weight loss in
6 months and to maintain this weight reduction within 2 years. Lifestyle
modifications (diet modification, increased physical activity, and weight
management) are recommended in all obese or overweight patients. Comprehensive
lifestyle intervention is recommended if no weight loss is seen with lifestyle
modifications. Preventive measures, including lifestyle modifications, decrease
the risk of cardiometabolic diseases, which in turn lowers the risk of severe
COVID-19 infection. The addition of pharmacological therapy is recommended if the
patient continues to gain weight or is unable to lose weight despite
comprehensive lifestyle interventions. Referral for bariatric surgery may be
considered if all other interventions fail and the patient has a BMI of ≥35
kg/m², or a BMI of 30–34.9 kg/m² with comorbidities.
Please see Obesity disease management chart for
further information.

Cardiac Rehabilitation
A comprehensive outpatient CV rehabilitation program is recommended for patients with ACS, chronic angina, post-coronary artery bypass surgery (CABG), or post-percutaneous coronary intervention. It is recommended for patients after ASCVD events and/or revascularization, and those with heart failure (particularly heart failure with reduced ejection fraction) to have an exercise-based cardiac rehabilitation and prevention program to improve patient outcomes.
Depression Management
Screening for depression is advisable in patients with recent CABG or MI. Management of depression has not been shown to improve CVD prognosis but may be advisable for its other clinical effects.
