Coronary heart disease (CHD) is a disease in which a waxy substance called plaque (plak) builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart muscle.
When plaque builds up in the arteries, the condition is called atherosclerosis (ATH-er-o-skler-O-sis). The buildup of plaque occurs over many years.
If the plaque ruptures, a blood clot can form on its surface. A large blood clot can mostly or completely block blood flow through a coronary artery. Over time, ruptured plaque also hardens and narrows the coronary arteries.
If the flow of oxygen-rich blood to your heart muscle is reduced or blocked, angina (an-JI-nuh or AN-juh-nuh) or a heart attack can occur.
Angina is chest pain or discomfort. It may feel like pressure or squeezing in your chest. The pain also can occur in your shoulders, arms, neck, jaw, or back. Angina pain may even feel like indigestion.
A heart attack occurs if the flow of oxygen-rich blood to a section of heart muscle is cut off. If blood flow isn’t restored quickly, the section of heart muscle begins to die. Without quick treatment, a heart attack can lead to serious health problems or death.
Over time, CHD can weaken the heart muscle and lead to heart failure and arrhythmias (ah-RITH-me-ahs). Heart failure is a condition in which your heart can't pump enough blood to meet your body’s needs. Arrhythmias are problems with the rate or rhythm of the heartbeat.
CHD is the most common type of heart disease. In the United States, CHD is the #1 cause of death for both men and women. Lifestyle changes, medicines, and medical procedures can help prevent or treat CHD. These treatments may reduce the risk of related health problems.
Acute phase treatment of ACS
Acute phase treatment of ACS includes a combination of anti-ischaemic and antithrombotic agents, with coronary reperfusion achieved using fibrinolysisand/or revascularization (percutaneous coronary intervention [PCI] or coronary artery bypass graft [CABG] surgery).
During an ACS event, platelets become activated and thrombin is generated, leading to potentially life threatening coronary artery occlusion.223, 224Antiplatelet and anticoagulant agents are routinely used during the acute phase of ACS treatment, for example:217, 221
In the chronic Phase an coronary angiogram should be done to determine the location of the blocks. This is an invasive procedure where a thin tube is introduced through a major artery and guided to the origins of the right and left coronary arterys and injecting a dye.The entire process is filmed and can be reviewed many times ,depending on the size, number and location the The block can be stented (using coronary Stents) or bypassed through surgery.
Life style changes are a must after the treatment
