What Is Heart Diseases? Symptoms Of Heart Attack & Prevention
What is Heart Disease?
Heart Disease refers to a variety of cardiovascular system disorders and conditions that affect the heart. Coronary Heart Disease (CHD), also called Coronary Artery Disease is the most common type of heart diseases.
The cardiovascular (CV) system is the circulatory system of the heart, blood vessels, and blood that is responsible for the transport of oxygen and nutrients, as well as waste products through the body.
The pumping heart provides the energy that makes the circulation of blood through the vascular system possible.
Coronary Heart Disease (Coronary Artery Disease)
The arteries that supply blood to the heart are called coronary arteries; they are located on the surface of the heart. There are three major coronary arteries, one on the right and two on the left.
Coronary heart disease happens when your coronary arteries become narrowed and hardened due to the buildup of cholesterol and other substances in the inner lining of the blood vessel, a process known as Atherosclerosis. When this happens the blood and oxygen supply to the heart muscle is restricted, especially during exercise, resulting in pain or discomfort in the chest area known as Angina, or even Heart Attack.
Angina: when the coronary arteries are partially blocked, the patient may experience chests pains
Heart Attack: when the coronary arteries become completely blocked, the patient will have a myocardial infarction. The most common reason for heart failure is a heart attack.
Other risking factors for coronary heart disease include smoking, high cholesterol, hypertension commonly known as high blood pressure, diabetes, and inadequate physical activity.
Protect your heart by adapting to a healthier lifestyle, including stopping smoking; changing to a diet of lower cholesterol, lower saturated fats, and high dietary fiber; cutting down salt intake; exercising more and doing meditations.
