Main risk factors for heart disease are high blood pressure, high cholesterol, and smoking.

Some of the main risk factors for heart disease are smoking, high blood pressure, and high cholesterol. You can reduce your risk of heart disease by making lifestyle changes to quit smoking and reduce your blood pressure and cholesterol.

Blood pressure higher than 140/90 mmHg for extended lengths of time may cause damage to the blood vessels. This damage increases the odds that plaque will accumulate in the arteries. Additionally, the artery walls thicken, which makes it more difficult for them to expand and contract the way they’re supposed to with changes in physical activity. You can lower your blood pressure by eating a healthy diet, limiting your salt intake, quitting smoking, maintaining a healthy weight, managing your stress levels, and getting regular physical exercise.

LDL cholesterol, also known as bad cholesterol, leads to plaque build-up in the arteries when levels are too high. Low levels of HDL cholesterol, also known as good cholesterol, can also be harmful to the heart. Your ideal blood cholesterol level is determined based on your age, gender, and medical history. For most individuals with coronary artery disease, the ideal LDL level is 100 mg/dL or less, and the ideal HDL level is greater than 40 mg/dL for men and 50 mg/dL for women. Eating a healthy diet, exercising, quitting smoking, and limiting your alcohol intake can help reduce your bad cholesterol.

Smoking introduces carbon monoxide, nicotine, and other hazardous chemicals into your lungs, heart, and blood vessels. Smoking makes the blood vessels constrict, increases blood pressure, and raises cholesterol. Smoking also reduces the amount of oxygen in bodily tissue, harms the lining of the blood vessels, promotes the growth of plaque in the arteries, and makes dangerous blood clots increasingly likely. Quitting smoking greatly reduces your risk of heart disease and several other medical conditions.
