Introduction Heart disease refers to a chronic condition where a person’s heart muscle does not perform its normal function properly. A reduction in blood flow to the muscles makes it difficult for the heart to pump enough blood into all vital organs. This can lead to strokes and other complications such as high blood pressure. Signs and Symptoms Signs and symptoms of heart disease include chest pain or discomfort, shortness of breath, low blood pressure, loss of appetite and nausea. These are usually present when someone has not been active (e.g., due to illness) or have too much alcohol. There may also be changes in blood pressure, blood sugar level, heart rate and the rhythm (skeletal system) of the heartbeat, which can be normal for some but abnormal for others. Also, people who present with any of these signs and symptoms should visit their doctor urgently. In addition, a complete medical history is important to detect pre-existing heart problems. Causes Heart disease can be caused by age, genetics, smoking, high blood pressure, obesity, being overweight and being female, high cholesterol, diabetes and poor diet. However, many other factors as well contribute to heart disease such as stress and family history. It may seem that heart disease often starts slowly and becomes more severe over time — this is not so. There are no symptoms or signs of heart disease in young children or animals. As people grow older, they develop a range of progressive cardiovascular diseases, including coronary artery disease, stroke and heart failure. For example, at least 50% of Americans have heart disease. The common types of heart disease are coronary artery disease, stroke and valvular heart disease. Coronary artery disease occurs when atherosclerosis — fatty, sticky plaques — forms on and around the arteries that supply blood to our heart muscle. Stroke occurs when the clot in the blood vessels blocks the arteries, causing blood to collect or pool inside the lungs. If this continues to happen for long periods of time, the body cannot bring enough oxygen, nutrients and other products of metabolism to your heart. This results in inflammation of the heart lining. A type 2 stroke is a sudden onset of clogged blood vessels in the brain and surrounding areas. At the same time this can cause damage to specific cells within the brain. Often these cells die from lack of blood supply. Stroke causes symptoms such as headache, dizziness, weakness, fatigue, muscle weakness and balance disturbance. When this happens, we may lose consciousness, change direction and feel faint. Blood Clots Stroke affects every part of the brain. Even though some areas of the brain do not get affected, there are some specific parts of the brain that are most vulnerable. During a stroke, blood flow is reduced to all the surrounding
