What is the pathology of heart disease?
coronary heart disease, also called coronary artery disease or ischemic heart disease, disease characterized by an inadequate supply of oxygen-rich blood to the heart muscle (myocardium) because of narrowing or blocking of a coronary artery by fatty plaques (see atherosclerosis).
What is pathophysiology of coronary heart disease?
Coronary artery disease is caused by plaque buildup in the wall of the arteries that supply blood to the heart (called coronary arteries). Plaque is made up of cholesterol deposits. Plaque buildup causes the inside of the arteries to narrow over time. This process is called atherosclerosis.
How does cardiovascular disease develop?
A diet that’s high in fat, salt, sugar and cholesterol can contribute to the development of heart disease. High blood pressure. Uncontrolled high blood pressure can result in hardening and thickening of your arteries, narrowing the vessels through which blood flows. High blood cholesterol levels.
What are the 4 types of Cardiovascular disease?
Four of the main types are described below.
- Coronary heart disease. Coronary heart disease occurs when the flow of oxygen-rich blood to the heart muscle is blocked or reduced.
- Strokes and TIAs.
- Peripheral arterial disease.
- Aortic disease.
What is the pathophysiology of chronic heart failure?
Heart failure is a medical condition characterized by reduced cardiac output (CO) and increased venous pressure, associated with underlying molecular changes and subsequent damage to and death of cardiac muscle cells. The body has its own ways of increasing lowered CO, which together make up the neurohumoral response.
Why is cardiovascular disease a health concern?
Heart disease is the leading cause of death for men, women, and people of most racial and ethnic groups in the United States. One person dies every 36 seconds in the United States from cardiovascular disease. About 655,000 Americans die from heart disease each year—that’s 1 in every 4 deaths.
What are the top 3 types of cardiovascular disease?
A List of Cardiovascular Diseases: The 5 Most Common
- Heart Attack. A heart attack, or myocardial infarction, usually tops the list of cardiovascular diseases in the United States — statistically and anecdotally.
- Stroke.
- Heart Failure.
- Arrhythmia.
- Heart Valve Complications.
What are some examples of cardiovascular disease?
What Are Cardiovascular Diseases?
- Abnormal heart rhythms, or arrhythmias.
- Aorta disease and Marfan syndrome.
- Congenital heart disease.
- Coronary artery disease (narrowing of the arteries)
- Deep vein thrombosis and pulmonary embolism.
- Heart attack.
- Heart failure.
- Heart muscle disease (cardiomyopathy)
What are the symptoms of cardiac disease?
Other symptoms of coronary artery disease include: Shortness of breath. Palpitations (irregular heart beats, or a “flip-flop” feeling in your chest) A faster heartbeat. Weakness or dizziness. Nausea. Sweating.
What are the risk factors of cardiac disease?
The major risk factors for cardiovascular disease include hypertension, smoking, poor diet, lack of exercise, diabetes and obesity.
What is the most common cardiovascular disease?
The most common cardiovascular disease is coronary heart disease. According to the American Heart Association, around 15,500,000 people in the United States are affected by it.
What are the risks of cardiovascular disease?
Some of the risk factors for cardiovascular disease include high blood pressure, high cholesterol, body weight/body mass index and high blood glucose. These numbers can serve as a wake-up call to jumpstart a healthier lifestyle.
