Coronary Heart Disease and Cardiovascular Disease are often used interchangeably, yet refer to different medical conditions. CHD refers to narrowed or blocked coronary arteries due to plaque build-up.
CVD encompasses many heart and blood vessel disorders including CHD, stroke, heart failure, and more. Knowing their differences is crucial for accurate diagnosis, effective treatment, preventive care, and health management.
What is Coronary Heart Disease (CHD)?
Coronary Artery Disease (CAD), also referred to as Coronary Heart Disease (CHD), is a condition marked by narrowing or blocking of coronary arteries supplying blood to the heart muscle, leading to reduced blood flow.
If these arteries become impaired then their impairment will reduce this vital supply thus resulting in an impaired heart muscle and reduced blood flow.
Narrowing or blockage occurs as a result of a build-up of fatty deposits on the inner walls of arteries, typically from plaque build-up. Over time, this buildup hardens and narrows arteries limiting oxygen-rich blood flow to heart muscle cells.
Reduced blood flow can result in symptoms like chest pain (angina) and shortness of breath during physical exertion, particularly with physical activity. A complete blockage could potentially lead to a heart attack, which is an emergency medical situation.
The development of CHD can often be caused by risk factors like high cholesterol levels, high blood pressure, smoking, diabetes, obesity, and leading an inactive lifestyle. Genetic factors and age also play a significant role.
Prevention and management strategies for CHD may include lifestyle modifications, medications to control contributing conditions, and surgical interventions such as angioplasty or bypass surgery. Recognizing and understanding risk factors is paramount to treating this serious disease.
What is Cardiovascular Disease (CVD)?
Cardiovascular Disease (CVD) refers to any condition affecting the heart and blood vessels, as well as related structures, including:
Coronary Heart Disease (CHD) refers to any narrowing or blockage of coronary arteries, leading to reduced blood flow to the heart.
Stroke: Any condition where part of the brain’s blood supply is interrupted or reduced and oxygen and nutrients cannot reach it, leaving brain tissue devoid of vital oxygen and nutrition.
Heart Failure: A condition wherein the heart cannot pump enough blood around its own circulatory system to meet needs, including inhalation.
Peripheral Artery Disease (PAD): Narrowing of peripheral arteries serving legs, stomach, arms, and head.
Heart Rhythm Disorders (HRDs): Issues related to the rhythm of the heartbeat such as arrhythmias that impair the pumping action of the heart. Congenital Heart Diseases are birth defects that alter the structure of the heart.
Hypertension: High blood pressure is a condition in which your heart must pump harder to pump blood around your body.
These conditions may share risk factors like high cholesterol, high blood pressure, obesity, diabetes, tobacco use, lack of physical activity, and poor diet.
CVD is one of the primary causes of death worldwide, underscoring its significance and prompt diagnosis by healthcare providers.
Treatment strategies must be tailored specifically for each type of cardiovascular disease, such as lifestyle modifications, medications or surgical interventions as needed, and ongoing monitoring and care from healthcare professionals.
