The nicotine in smoke causes less oxygen to the heart, higher blood pressure and heart rate more blood clotting, damage to cells that line coronary arteries and other blood vessels

Atherosclerosis, a type of heart disease, is a process that occurs when there is an excessive buildup of cholesterol in the artery walls. Blood flow to the heart muscle is reduced or restricted as the arteries constrict.

Several cardiac conditions, such as arrhythmias, congenital heart disease, cardiomyopathy, and excessive blood cholesterol, can be inherited. There may be inherited genetic risk factors for coronary artery disease, which can cause heart attacks, strokes, and heart failure.

The symptoms of coronary heart disease cannot be cured, but medication can help manage them and lower the risk of complications like heart attacks. Lifestyle modifications like regular exercise and quitting smoking are examples of possible treatments.

The primary outcome is the occurrence of a major cardiac complication, which is defined as congestive heart failure, cardiogenic pulmonary edema, stable or unstable angina, myocardial infarction, severe arrhythmia (ventricular tachycardia or fibrillation), cardiac arrest, cardiac death, or sudden death.

Signs and symptoms of a heart attack in men and women: Chest pain or distress; Breathlessness Discomfort or pain in the mandible, neck, back, arm, or shoulder; Feeling nauseated, dizzy, or unusually exhausted.

Heart attacks are primarily caused by coronary artery disease (CAD). Infrequently, a severe spasm or sudden contraction of a coronary artery can obstruct blood supply to the heart muscle.
