This document discusses several types of cardiovascular diseases including atherosclerosis, angina pectoris, arrhythmias, and hypertension. It describes the symptoms, risks, and what each condition is for each type of cardiovascular disease. Atherosclerosis is a buildup of plaque in the arteries that can restrict blood flow. Angina pectoris causes chest pain from reduced blood flow to the heart. Arrhythmias refer to irregular heart rhythms. Hypertension, also called high blood pressure, damages the body over time if left uncontrolled. Smoking, high cholesterol, diabetes, and lack of exercise are among the main risk factors for cardiovascular diseases.
