Coronary Artery Diseases
Coronary artery disease (CAD), also known as ischemic heart disease (IHD) is a group of diseases that includes: stable angina, unstable angina, myocardial infarction, and sudden cardiac death. It is within the group of cardiovascular diseases of which it is the most common type. A common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw. Occasionally it may feel like heartburn. Usually symptoms occur with exercise or emotional stress, last less than a few minutes, and get better with rest. Shortness of breath may also occur and sometimes no symptoms are present. The first sign is occasionally a heart attack. Other complications include heart failure or an irregular heartbeat.
Artheriosclerosis is loss of elasticity, thickening, hardening of arterial walls, narrowing of the arteries silently and slowly blocks arteries, putting blood flow at risk.
Artherosclerosis can create life-threatening blockages without you ever feeling a thing. Artherosclerosis precedes angina pectoris, myocardial infarction, heart attacks, strokes, and peripheral vascular disease.
Chest Pain/Angina Pain
Angina is chest pain or discomfort caused when your heart muscle doesn't get enough oxygen-rich blood. It may feel like pressure or squeezing in your chest. The discomfort also can occur in your shoulders, arms, neck, jaw, or back. Angina pain may even feel like indigestion.
But, angina is not a disease. It is a symptom of an underlying heart problem, usually coronary heart disease (CHD).There are many types of angina, including microvascular angina, Prinzmetal's angina, stable angina, unstable angina and variant angina. View an animation of angina.
Heart attack/Myocardial Infarction
Myocardial infarction (MI) or acute myocardial infarction (AMI), commonly known as a heart attack, occurs when blood flow stops to a part of the heart causing damage to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw. Often it is in the center or left side of the chest and lasts for more than a few minutes. The discomfort may occasionally feel like heartburn. Other symptoms may include shortness of breath, nausea, feeling faint, a cold sweat, or feeling tired. Women more likely than men. An MI may cause heart failure, an irregular heartbeat (including serious types), cardiogenic shock, or cardiac arrest.
