Heart disease is a broad term used to describe conditions that affect the heart and blood vessels. It is one of the leading causes of death worldwide, but the good news is that many forms of heart disease are preventable and manageable with the right care and lifestyle choices.
What Is Heart Disease?
Heart disease includes disorders such as coronary artery disease, heart attacks, heart failure, arrhythmias (irregular heartbeat), and valve diseases. The most common type is coronary artery disease, caused by the buildup of fatty deposits (plaque) in the arteries that supply blood to the heart.
Common Causes
| Category | Common Cause | How It Affects the Heart |
| Lifestyle Factors | Smoking | Damages blood vessels and reduces oxygen supply |
| Lifestyle Factors | Unhealthy diet | Increases cholesterol, leading to artery blockage |
| Lifestyle Factors | Physical inactivity | Raises risk of obesity, diabetes, and high BP |
| Lifestyle Factors | Excessive alcohol | Weakens heart muscle and raises BP |
| Medical Conditions | High blood pressure | Puts extra strain on heart and arteries |
| Medical Conditions | High cholesterol | Causes plaque buildup in arteries |
| Medical Conditions | Diabetes | Damages blood vessels and nerves controlling the heart |
| Medical Conditions | Obesity | Increases workload on the heart |
| Medical Conditions | Chronic stress | Raises BP and triggers unhealthy habits |
| Genetic Factors | Family history | Increases inherited risk |
| Age-Related | Aging | Arteries stiffen and heart efficiency declines |
| Other Factors | Poor sleep | Affects BP, weight, and heart rhythm |
| Other Factors | Inflammation | Contributes to artery damage and clot formation |
Basics Facts About Heart Attacks
Cardiovascular disease (CVD) kills more people annually than any other cause. Furthermore, three-quarters of heart disease and heart attacks occur in low- and middle-income nations. The risk of emerging circulatory disease (CVD) rises with an unhealthy diet characterized by low intake of fruits and vegetables and high intake of salt, sugar, and fat. Poor diet contributes to obesity and being overweight, risk factors for circulatory disease. In addition, people who do not get sufficient exercise are 20-30% more likely to die sooner than people who get enough exercise. Therefore, lack of exercise is a significant risk factor for the development of heart diseases, cancer, and diabetes. Contact with tobacco products is estimated to be responsible for 10% of all circulatory deaths.

WHO Response
In our region, the WHO Division of Non-communicable Diseases and Mental Health organizes HEARTS in the World, which disseminates best practices in the prevention and treatment of cardiovascular disease to impact. The burden of these illnesses and meet the goals for Getting Closer to Sustainable Development for 2030. In addition, HEARTS in the World is a national initiative led by Ministries of Health, with the participation of local formations and technical delivery from WHO. Also, aim to flawlessly and progressively mix with existing health services to ease the uptake of established methods to promote cardiovascular disease (CVD). Deterrence and control do alter care delivery by refining high blood pressure control and endorsing secondary deterrence, with a focus on primary care.
Types Of Cardiovascular Disease
1. Coronary Artery Disease
Coronary Artery Disease (CAD) is a common type of heart disease and occurs when atherosclerotic plaque builds up in the arteries key to the heart—also called coronary artery disease (CHD). The heart can’t get sufficient blood and oxygen when the arteries narrow. For example, a closed lane can cause a heart attack. Over time, coronary artery disease can weaken the heart muscle and lead to heart failure or abnormal heart rhythms.
2. Heart Failure
Heart failure chance when the heart muscle becomes stiff or weak. It can’t pump enough oxygen-rich blood, leading to symptoms throughout the body. The disease can affect only the right or left side of the heart. Both halves of the heart are often involved. High blood pressure and coronary are common causes of heart failure.
3. Arrhythmias
Arrhythmias are problems with the heart rate (pulse) or rhythm. It happens when the heart’s electrical system fails. As a result, your heart can beat too quickly, slowly, or irregularly. Specific heart problems, such as heart attack or heart failure, can source issues with the heart’s electrical system. Some people with arrhythmia by birth.
4. Heart Valve is a Heart Disease
Heart valve occurs when one of the four heart valves fails. As a result, blood may leak through the valve in the wrong direction (called regurgitation). The valve may not open wide enough and block blood flow (called stenosis). The most common symptom is an unusual heartbeat, known as a heart murmur. In addition, specific heart problems, such as a heart attack, heart disease, or an infection, can cause heart valve. Some people birth heart valve defects.
5. Peripheral Artery Disease
Peripheral artery disease chance when the arteries in the legs and feet narrow due to plaque buildup; narrowed lanes reduce or block blood flow. Damage can occur when blood and oxygen cannot reach the legs, nerves, and tissue.
6. High Blood Pressure:[Hypertension] Causes Heart Disease
High blood pressure is a cardiovascular disease that can help with other problems such as heart attack, heart failure, and stroke.
7. Stroke Is a Heart Disease
A stroke is an effect of a lack of blood supply to the brain. It can happen due to the movement of a blood clot in the brain’s blood vessels or bleeding in the brain.
8. Congenital Heart Disease
Congenital heart disease is a problem in heart structure and function present from birth. The term can describe many problems affecting the heart. In addition, most common form of congenital disability.
