Cardiovascular disease is a class of diseases that involve the heart or blood vessels.
The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system.
The blood vessels are the part of the circulatory system that transports blood throughout the human body.
Cardiovascular Disease Overview by Armando Hasudungan
Cardiovascular disease includes coronary artery diseases such as angina and myocardial infarction.
Coronary artery disease, also known as ischemic heart disease, is a group of diseases that includes: stable angina, unstable angina, myocardial infarction, and sudden cardiac death.
Myocardial infarction or acute myocardial infarction, commonly known as a heart attack, occurs when blood flow stops to a part of the heart causing damage to the heart muscle.

Other CVDs are stroke, heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, heart arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease, and venous thrombosis.
Heart failure, often referred to as congestive heart failure, occurs when the heart is unable to pump sufficiently to maintain blood flow to meet the body's needs.
Congenital heart defect, also known as a congenital heart anomaly or congenital heart disease, is a problem in the structure of the heart that is present at birth.
Cardiac arrhythmia, also known as cardiac dysrhythmia or irregular heartbeat, is a group of conditions in which the heartbeat is irregular, too fast, or too slow.
The underlying mechanisms vary depending on the disease in question.
Coronary artery disease, stroke, and peripheral artery disease involve atherosclerosis.
Atherosclerosis is a specific form of arteriosclerosis in which an artery-wall thickens as a result of invasion and accumulation of white blood cells and proliferation of intimal-smooth-muscle cell creating a fibrofatty plaque.
This may be caused by high blood pressure, smoking, diabetes, lack of exercise, obesity, high blood cholesterol, poor diet, and excessive alcohol consumption, among others.
Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have a negative effect on health.
In chemistry, an alcohol is any organic compound in which the hydroxyl functional group is bound to a saturated carbon atom.
High blood pressure results in 13% of CVD deaths, while tobacco results in 9%, diabetes 6%, lack of exercise 6% and obesity 5%.
Death is the termination of all biological functions that sustain an organism.
Rheumatic heart disease may follow untreated strep throat.
It is estimated that 90% of CVD is preventable.
Prevention of atherosclerosis involves improving risk factors through: healthy eating, exercise, avoidance of tobacco smoke and limiting alcohol intake.
Treating high blood pressure, blood lipids and diabetes is also beneficial.
Treating people who have strep throat with antibiotics can decrease the risk of rheumatic heart disease.
Antibiotics, also called antibacterials, are a type of antimicrobial drug used in the treatment and prevention of bacterial infections.
The effect of the use of aspirin in people who are otherwise healthy is of unclear benefit.
Aspirin, also known as acetylsalicylic acid, is a medication used to treat pain, fever, and inflammation.
The United States Preventive Services Task Force recommends against its use for prevention in women less than 55 and men less than 45 years old; however, in those who are older it is recommends in some individuals.
The United States Preventive Services Task Force is "an independent panel of experts in primary care and prevention that systematically reviews the evidence of effectiveness and develops recommendations for clinical preventive services."
Treatment of those who have CVD improves outcomes.
Cardiovascular diseases are the leading cause of death globally.
This is true in all areas of the world except Africa.
Together they resulted in 17.3 million deaths in 2013 up from 12.3 million in 1990.
Deaths, at a given age, from CVD are more common and have been increasing in much of the developing world, while rates have declined in most of the developed world since the 1970s.
A developed country, industrialized country, or "more economically developed country", is a sovereign state that has a highly developed economy and advanced technological infrastructure relative to other less industrialized nations.
A developing country, also called a third world country, a less developed country or underdeveloped country, is a nation with a less developed industrial base and a low Human Development Index relative to other countries.
Coronary artery disease and stroke account for 80% of CVD deaths in males and 75% of CVD deaths in females.
