Types of Heart Diseases[edit | edit source]
Heart disease encompasses several conditions:
Coronary heart disease: Occurs due to the accumulation of atheromatous plaques within the arteries supplying the myocardium. Ischaemic heart disease: Characterized by reduced blood supply to the heart. Cardiovascular disease: Encompasses conditions affecting the heart and/or blood vessels. Notable diseases under this umbrella include diabetes, high blood pressure, and high cholesterol. Pulmonary heart disease: Involves failure of the heart's right side. Hereditary heart disease Hypertensive heart disease Inflammatory heart disease
Coronary Artery Disease (CAD)[edit | edit source]
Coronary artery disease is a result of plaque buildup in the coronary arteries, primarily composed of cholesterol deposits. This buildup, also known as atherosclerosis, narrows the arteries over time.
This narrowing can reduce blood flow, leading to symptoms like angina, which is chest pain or discomfort. Angina is the most frequent manifestation of CAD. Progressed CAD can cause heart muscle weakening, potentially leading to heart failure or irregular heart rhythms, known as arrhythmias.
Heart Attack Signs and Symptoms[edit | edit source]
Notable symptoms of a heart attack include:
Jaw, neck, or back pain or discomfort. A sensation of weakness, light-headedness, or faintness. Chest pain. Arm or shoulder pain or discomfort. Breathing difficulties. Uncommon symptoms can involve unusual fatigue, nausea, or vomiting. Notably, these are more frequent in women.
Emergency Procedure: If these symptoms manifest, immediately call 9-1-1. Prompt emergency room visits can prevent or minimize heart muscle damage. CPR or defibrillation might be required in some instances, and early treatment increases survival chances.
Diagnosing CAD[edit | edit source]
For CAD risk assessment, health professionals might evaluate blood pressure, cholesterol, and sugar levels. Risk factors include being overweight, inactive lifestyle, poor diet, and smoking. Family history also plays a pivotal role.
Tests for CAD[edit | edit source]
Standard tests for diagnosing CAD are:
