Heart Diseases

Heart diseases Definition of Heart Diseases • Heart disease: Any disorder that affects the heart . Atherosclerosis • General term for a condition characterized by thickening, hardening, and loss of elasticity of the walls of the blood vessels. • People with atherosclerosis have a buildup of cholesterol and fat that makes their arteries narrower. Those deposits are called plaque. • As the vessel walls thicken, the passageways through the vessels narrow, decreasing the blood supply to the affected region. Atherosclerosis • The deposition of materials along the arterial walls What are the some of the Causes of Heart Diseases? • Causes of Heart Diseases Heart disease is not contagious — you can't catch it like you can catch the flu. Some risk factors: – The Age . – Heredity – High blood pressure . – Diabetes: High blood glucose levels over time can lead to increased deposits of fatty materials on the insides of the blood vessel walls – Obesity and eating not healthy food . – Physical inactivity . – Elevated levels of cholesterol . – Alcohols + smoking Angina • is the medical term for chest pain or discomfort due to coronary heart disease. • Chest pain resulting from reduced oxygen supply to the heart muscle. • Thus, it is a condition in which the heart muscle does not receive enough blood causing severe pain in the chest area. • This results when the arteries that supply the heart muscle with oxygenated blood are narrowed. Angina Symptoms • uncomfortable pressure, • fullness, • squeezing or pain in the center of the chest. • The discomfort also may be felt in the neck, jaw, shoulder, back or arm. When does angina occur? • Angina often occurs when the heart needs more blood. – For example, running to catch a bus could trigger an attack of angina while walking might not. – Angina may happen during exercise, strong emotions or extreme temperatures. Some people, such as those with a coronary artery spasm, may have angina when they're resting. Heart Attacks Heart attacks are the symptoms that occur when the patient's blood decrease in force in the coronary arteries feeding the heart muscles, which are often the result of the narrow coronary arteries, which prevents access blood adequately. • • • • • • Symptoms of Heart Diseases tightness, discomfort heaviness, pressure or squeezing shortness of breath sweating or weakness nausea and/or vomiting denial, refusing to admit that anything is wrong • dizzying , tiredness, headache • stressed and pain in chest and left shoulder.

Aspirin or Medicine. Heart Diseases & Sport • Regular exercises help to increase the percentage of the good cholesterol (HDL) which help to remove the bad cholesterol (LDL) from arteries. The increase of the bad cholesterol in the blood leads to drifting fats on the arteries walls and this leads to stopping blood supply. • Sport help to decrease blood pressure. If your blood pressure is high you are more susceptive than other to heart diseases. • Exercises help you to reduce your weight. Obesity increases the strain on the heart and it is increase the possibility of having heart diseases by increasing blood pressure and cholesterol percentage. Sport for Heart Patients The appropriate sport for heart patients: • Swimming ( not too much). • Slow running. • Walking The inappropriate sports for heart patients: • Weight lift. • Running for long time. • Boxing. • Climbing.
