Many kinds of heart disease exist, which affect different parts of the organ and can manifest in different ways.
Coronary Artery Disease
Coronary heart disease describes arteries that supply the heart with nutrients and oxygen as being diseased or damaged, typically due to plaque deposits of cholesterol. These plaques build up and narrow the coronary arteries, leading to a heart attack.
High Blood Pressure
Also called hypertension, high blood pressure is a risk factor for more than heart disease. High blood pressure can damage the body for years before symptoms develop. This can lead to a disability, poor quality of life, or even a fatal heart attack.
Cardiac arrest is the abrupt loss of heart function in someone who may or may not have been diagnosed with heart disease. It can have acute onset or can occur in the wake of other symptoms. Cardiac arrest oftentimes proves fatal if the patient does not receive immediate medical care.
Congestive Heart Failure
Congestive heart failure describes a chronic and progressive condition that affects the pumping of the heart muscles. Certain conditions, such as coronary artery disease or high blood pressure, can gradually leave the heart to weak to fill and pump correctly.
Arrhythmia is an irregular heartbeat. This can occur in several different ways. Arrhythmias include tachycardia (too fast), bradycardia (too slow), premature ventricular contractions, fibrillation (irregular beating), or additional and abnormal beats. Arrhythmias occur when the electrical impulses in the heart do not work properly.
Peripheral Artery Disease
Peripheral artery disease involves the narrowing of the peripheral artery serving the legs, stomach, arms, and head. It most commonly affects the arteries in the legs. This happens when plaque builds up in the arteries that carry blood to the peripheral parts of the body, which can lead to a heart attack.
A stroke occurs when a blood vessel bringing oxygen and nutrients to the brain is blocked by a clot (ischemic stroke) or it ruptures (hemorrhagic stroke), cutting off blood and oxygen flow to that part of the brain. This leads to a halt in blood flow to the brain and brain cell death.
Congenital Heart Disease
This condition describes the deformities of the heart that have been present since birth. Some examples include septal defects (a hole between the two chambers of the heart), obstruction defects (the flow of blood through the chambers is partially or fully blocked), or cyanotic heart disease (a defect caused by a shortage of oxygen around the body).
