Cardiovascular diseases are a group of disorders of the heart and blood vessels. The World Health Organization (WHO) estimated that 19.8 million people died from cardiovascular diseases in 2022 alone, accounting for approximately 32% of all global deaths. Of these deaths, 85% were due to heart attacks and strokes. Some common cardiovascular diseases include;

Ischemic Heart Disease (IHD): Ischemic heart disease, also known as coronary artery disease, occurs when the blood supply to the heart is restricted. This reduction in blood flow decreases the delivery of oxygen to the heart muscle. Common symptoms of ischemic heart disease include chest pain (angina), shortness of breath (this is particularly noticeable during physical activity), fatigue and discomfort or pain in the chest, arms, legs, or jaw.

Stroke: A stroke occurs when the blood supply to the brain is interrupted, either due to a blockage (known as an ischemic stroke) or bleeding (referred to as a hemorrhagic stroke). Common symptoms include sudden weakness or numbness, difficulty speaking or understanding speech, changes in vision, severe headaches, and dizziness. Strokes are a leading cause of death and disability, responsible for approximately 6.6 million deaths worldwide.

Hypertensive Heart Disease: This condition develops when long-term high blood pressure exerts excessive strain on the heart, leading to issues with heart rhythm and the potential for heart failure. High blood pressure is a significant risk factor for cardiovascular diseases, contributing to around 10 million deaths each year. Often, hypertensive heart disease may not present noticeable symptoms until it reaches advanced stages. However, some possible symptoms include shortness of breath, fatigue, and swelling in the legs, ankles, or feet.

Valve Disease: Valve disease refers to conditions that affect the heart valves, which control blood flow between the heart's chambers and major blood vessels. Symptoms include fatigue, shortness of breath, chest pain, and swelling in the legs, ankles, or feet. Valve disease can lead to conditions such as stenosis, regurgitation, and valve damage.

Heart Failure: Heart failure occurs when the heart is unable to pump enough blood to meet the body's needs. This can lead to serious complications, including death. Symptoms of heart failure include fatigue, rapid weight gain, shortness of breath, and swelling in the legs, ankles, or feet.

Causes of Cardiovascular Diseases

Cardiovascular diseases arise from a combination of genetic, lifestyle, and environmental factors. By understanding these causes, individuals can take proactive steps to lower their risk of developing heart diseases and promote overall cardiovascular health. Here are some common contributors:

Genetic Factors:

• Family History: A family history of cardiovascular diseases can increase an individual’s risk.
• Genetic Predisposition: Certain genetic conditions may heighten the likelihood of developing cardiovascular diseases.

Lifestyle Factors

• Unhealthy Diet: A diet high in saturated fats, trans fats, salt, and sugar can contribute to cardiovascular diseases
• Physical Inactivity: Lack of regular physical activity can increase risk.
• Smoking: Tobacco use is a major risk factor for cardiovascular diseases.
• Excessive Alcohol Consumption: Overconsumption of alcohol can raise blood pressure and contribute to cardiovascular diseases.

Physiological Factors

High Blood Pressure: Hypertension can damage blood vessels, increasing the risk of cardiovascular diseases.

High Cholesterol: Elevated levels of low-density lipoprotein (LDL) cholesterol may lead to plaque buildup in the arteries.

Diabetes: High blood sugar levels can harm blood vessels and nerves.

Obesity: Carrying excess weight can elevate the risk of developing cardiovascular diseases.

Environmental Factors:

• Air pollution: Poor air quality can increase the risk of cardiovascular disease.
• Stress: Chronic stress can elevate blood pressure and encourage unhealthy behaviours.

How Can One Ensure Heart Health?

Incorporating the following habits into one’s lifestyle can significantly reduce the risk of heart disease and help maintain overall cardiovascular health:

• Eat a Heart-Healthy Diet: Focus on whole, unprocessed foods such as fruits, vegetables, whole grains, lean proteins, and healthy fats. The Mediterranean diet is a great example.
• Quit Smoking: Stop smoking and avoid exposure to secondhand smoke.
• Limit Alcohol Consumption: Drink in moderation, defined as up to one drink per day for women and up to two drinks per day for men.
• Stay Physically Active: Engage in regular aerobic exercise, such as brisk walking, cycling, or swimming, for at least 150 minutes each week.
• Maintain a Healthy Weight: Aim for a body mass index (BMI) between 18.5 and 24.9 to lower the risk of heart disease.
• Manage Stress: Participate in stress-reducing activities like meditation, yoga, or deep breathing exercises.
• Get Enough Sleep: Aim for 7 to 8 hours of sleep each night to help regulate stress and support cardiovascular health.
• Monitor and Manage Blood Pressure: Check your blood pressure regularly and collaborate with your healthcare provider to manage it if it's high.
• Control Cholesterol Levels: Get regular lipid profiles and work with your healthcare provider to manage high cholesterol if necessary.
• Stay Hydrated: Drink plenty of water throughout the day to help maintain blood flow and overall health.
• Get Regular Check-Ups: Schedule regular health check-ups with your healthcare provider to monitor your heart health and address any concerns.

World Heart Day aims to raise awareness about cardiovascular diseases by educating the public on their risks and symptoms. It promotes prevention through healthy lifestyle choices and encourages regular cardiac check-ups for early detection. The day also unites communities, healthcare providers, and governments in the global fight against heart diseases.
