Heart disease is quickly rising to the top of the cause-of-death ranking worldwide. However, the fact that a startling majority of these cardiac disorders are mainly preventable is more worrisome. Understanding the causes of heart disease and how to prevent it is more important than ever. Sedentary lifestyles, unhealthy diets, unchecked stress, ignorance, and physical inactivity are all significant factors contributing to such an increase. Proactive steps, including living a heart-healthy lifestyle, staying informed, and recognizing early warning symptoms, can make all the difference. This blog will provide vital information on heart disease and practical advice on protecting your most vital organ before it's too late.
What Is Heart Disease?
There are several conditions that can impact your heart. Such conditions are collectively called heart diseases. People often associate heart diseases with its most prevalent form, that is a coronary artery disease (CAD), and the potential for heart attacks it might cause. However, issues with the electrical system of the heart, heart valves, or heart's muscle can also result in significant malfunctioning of the heart.
Your heart struggles to pump enough blood, oxygen, and nutrients to your body when it isn't functioning properly. Factually, your heart provides the energy that maintains the overall functioning of your body. Every system in your body is impacted if there is an issue supplying the necessary fuel. Medication and lifestyle modifications can prevent heart disease and maintain heart health.
Common Types of Heart Disease
| Category | Subcategory | Description |
| Heart Artery Disorders | Coronary Artery Disease (CAD) | Plaque buildup causing blockage or narrowing of coronary arteries, reducing blood flow to the heart muscle |
| Ischemic Heart Disease | Reduced blood supply causes death of heart tissues, affecting overall heart function | |
| Heart Muscle Disorders | Dilated Cardiomyopathy | Heart enlargement and inefficiency to pump blood adequately. |
| Hypertrophic Cardiomyopathy | Thickening of the heart muscle,obstructing the blood flow | |
| Restrictive Cardiomyopathy | Loss of elasticity of heart tissue | |
| Heart Pumping Disorders | Left-sided Heart Failure | Affects the heart’s ability to pump blood to the body. Common in hypertension and CAD. |
| Right-sided Heart Failure | Often caused by left-sided failure or lung disease, leading to fluid buildup in the body. | |
| Heart Rhythm Disorders | Atrial Fibrillation (AFib) | Irregular, rapid heart rhythm that increases the risk of stroke. |
| Bradycardia | Slower-than-normal heart rate, which can cause fatigue and dizziness. | |
| Tachycardia | Abnormally fast heart rate, which can be dangerous if persistent. | |
| Heart Valve Disorders | Aortic Valve Stenosis | Narrowing of the aortic valve, reducing blood flow from the heart to the body. |
| Mitral Valve Regurgitation | Leakage of blood backward through the mitral valve with each heartbeat. | |
| Tricuspid or Pulmonary Valve Disease | Less common disorders affecting other heart valves. | |
| Congenital Defects | Atrial Septal Defect (ASD) | A hole in the wall between the heart's upper chambers. |
| Ventricular Septal Defect (VSD) | A hole in the wall between the lower chambers, affecting blood flow. | |
| Tetralogy of Fallot | A combination of four heart defects present at birth, requiring surgery. | |
| Heart Lining Disorders | Pericarditis | Inflammation of the pericardium causing chest pain and fluid buildup. |
| Pericardial Effusion | Accumulation of fluid in the pericardial sac. | |
| Constrictive Pericarditis | Long-term inflammation leading to thickening and scarring of the pericardium. | |
| Major Vessel Disorders | Aortic Aneurysm | A bulge in the wall of the aorta that can rupture if not treated. |
| Aortic Dissection | A tear in the inner layer of the aorta wall, considered a medical emergency. |
