Why Study Coronary Heart Disease?
Coronary heart disease is a major factor Leading cause of death in the United States claiming
370,000 lives annually. Easily preventable and controllable through health
education on healthy eating habits and physical activity to reduce the risk factors.
Important because there is a high rate of coronary heart disease in underserved communities
Most prevalent among residents of underserved communities, with habits originating during childhood
Educate communities to limit risk factors.
Overview
Coronary heart disease (CHD) is a narrowing of the small blood vessels that supply blood and oxygen to the heart.
Alternative name of coronary heart disease: Heart disease, Coronary heart disease, Coronary artery disease; Arteriosclerotic heart disease; CHD; CAD
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.
History of Coronary Hearth Diseases
The earliest date for the medical communities awareness of coronary heart disease and arteries narrowing is unknown.
- Leonardo da Vinci (1452–1519) investigated coronary arteries.
- William Harvey (1578–1657) is credited with discovering how the blood moves: from the right ventricle of the heart through the lung and into the aorta, then the peripheral vessels, and back into the lung.
- Subsequently, Friedrich Hoffmann (1660–1742), chief professor of cardiology at the University of Halle, noted that coronary heart disease started in the “reduced passage of the blood within the coronary arteries.”

Cause Of The Coronary Heart Diseases.
Coronary heart disease is caused by the buildup of plaque in the arteries to your heart. Fatty material and other substances form a plaque buildup on the walls of coronary arteries. The coronary arteries bring blood and oxygen to the heart.This buildup causes the arteries to narrow As a result, blood flow to the heart can slow down or stop which may lead to the risks factors.Working hard to eliminate the risk factors can save lives.
What are the Symptoms Of Heart Diseases?
Symptoms may be very noticeable, or alternatively imperceptible. Hearth disease is often asymptomatic in its early stages.Chest pain or discomfort (angina) is the most common symptom. Affected individuals feel pain when the heart is not getting enough blood or oxygen. Though the pain intensity varies.Manifestation of this pain includes:Sensation if someone is squeezing ones heart. Often noticeable under ones breast bone (sternum). Pain also may radiate to the neck, arms, stomach, or upper back.The pain most often occurs with activity or emotion. It goes away with rest or a medicine called nitroglycerin.Other symptoms include shortness of breath and fatigue with activity (exertion).Some people have symptoms other than chest pain, such as: Fatigue, Shortness of breath, General weakness
When to Contact a Medical Professional
If you have any risk factors for CHD, talk to your doctor about prevention and possible treatment steps.
Call your health care provider, call the local emergency number (such as 911), or go to the emergency room right away if you experience:
Angina or chest pain Shortness of breath Symptoms of heart attack
Prevention Of Heart Disease! Life style change Follow a healthy diet Physical Exercise Dietary Approaches to
stop hypertension Maintain a healthy weight Quit smoking Manage stress
