- Before the atherosclerosis sets in
- Before atherosclerosis leads to a cardiovascular event, such as a heart attack
- After the first, but before any subsequent cardiovascular events
- Age —For men, age 45 or older; for women, age 55 or older.
- Race —African Americans have a greater incidence of hypertension than Caucasians, and therefore a higher risk of developing CVD. Others at increased risk include Mexican Americans, Native Americans, native Hawaiians, and some Asian Americans.
- Family History —First-degree relative (father, mother, sister, brother) with premature heart disease (males younger than 55, females younger than 65).
- Gender —Men tend to suffer cardiovascular events sooner than women. After menopause, however, cardiovascular risk in women quickly catches up to that in men.
- Smoking —Smokers are twice as likely to have a heart attack as nonsmokers. Cigarette smoking is also the biggest risk factor for sudden cardiac death. Even nonsmokers can increase their risk of heart disease if they are constantly exposed to cigarette smoke.
- High blood cholesterol — High total and LDL cholesterol levels and low HDL cholesterol levels increase the risk of atherosclerosis, coronary heart disease, and stroke. In general, a total cholesterol level less than 200 mg/dL (5.2 mmol/L) , an LDL cholesterol level less than 100 mg/dL (2.6 mmol/L), and an HDL cholesterol level greater than 60 mg/dL (1.6 mmol/L) are considered desirable.
- High blood pressure (hypertension) — High blood pressure accelerates the progression of atherosclerosis and increases the risk of coronary heart disease, stroke, and congestive heart failure. Hypertension is defined as a blood pressure equal to or above 140/90 mmHg. However, individuals with blood pressure in the high-normal range (around 130/85 mmHg) are at increased risk of becoming hypertensive and should take steps to lower their blood pressure.
- Physical inactivity —A sedentary lifestyle increases risk for coronary heart disease, while regular physical activity can prevent it. Exercise also helps control other CVD risk factors, including high LDL-cholesterol, low HDL-cholesterol, type 2 diabetes, obesity, and high blood pressure.
- Obesity and overweight— Excess body fat, particularly in the abdominal region, is associated with an increased risk for heart disease and stroke. Surplus weight puts additional strain on your heart, and raises blood pressure, blood cholesterol and the risk of type 2 diabetes.
- Type 2 Diabetesand prediabetes —Type 2 diabetes is a major risk factor for cardiovascular disease. About two-thirds of people with diabetes die of some type of heart or blood vessel disease. Glucose intolerance prior to the onset of type 2 diabetes can also place you at increased risk.
- Excess alcohol —Drinking too much alcohol can raise your blood pressure, cause heart failure, and lead to stroke. It can contribute to high triglycerides (fats in the blood) and obesity, and may predispose to arrhythmias.
- Stress —Although it remains unclear exactly how much psychological stress contributes to the development of CVD, if you have already been diagnosed with a cardiovascular condition, you could benefit from stress management.
Emerging risk factors—
The association of these risk factors with CVD is less well established, but many authorities believe they will become clinically important in the near future.
- C-reactive protein —C-reactive protein is a marker of inflammation. High levels of the protein have been associated with increased risk of heart disease and stroke, even when total and LDL-cholesterol levels are low. It is not yet known how to reduce C-reactive proteins.
- Homocysteine —Homocysteine is an amino acid (building block of protein) that appears to contribute to atherosclerosis and blood clotting. High levels of homocysteine have been linked to increased risk of heart disease. Folic acid in the diet is effective at reducing homocysteine levels.
- Medical History —You physician will ask you questions about current and previous illnesses, past surgeries and hospitalizations, medications, diet and other lifestyle factors, social history, and family history in order to gauge your CVD risk.
—Your doctor may assess the following:
- Body Mass Index — BMI is a measurement of body mass that takes into account both height and weight.
- Fat Distribution — This is usually measured as a waist-to-hip ratio. Carrying more fat around your abdomen and upper body (an “apple” shape) puts you at greater risk for heart disease, high blood pressure, and diabetes.
Blood Pressure Measurement
—Blood pressure is measured using a cuff around your arm and a device called a sphygmomanometer. Blood pressure has a tendency to fluctuate and needs to be measured several times before a diagnosis of hypertension can be made.

—For the following tests, blood may be drawn in your doctor’s office or in a laboratory. The blood is then sent to the laboratory for analysis, and you should receive the results within one week.
- Lipid Profile — A complete lipid profile will measure the levels of total cholesterol, LDL and HDL cholesterol, and triglycerides in your blood.
- Blood Sugar/Glycohemoglobin (HBA1C) —These tests are used to both screen for diabetes and monitor the progress of diabetes treatment.
- Exercise Tolerance or Stress Test — Using an electrocardiogram (ECG) to measure the heart’s electrical activity at rest provides limited information about the oxygen supply to the heart. A stress test, therefore, is often used to evaluate the presence and severity of cardiovascular disorders as the heart responds to the additional demand for oxygen during physical activity.
