What is Cardiovascular Disease?
Cardiovascular disease (CVD), also known as heart disease, is a broad term encompassing conditions affecting the heart and blood vessels. It's a major global health concern. Understanding what it is, and how to mitigate your risk, is the first step towards a healthier heart.
What exactly is cardiovascular disease? It's a catch-all phrase for several conditions, including:
- Coronary artery disease (CAD): The most common type of CVD, involving plaque (fatty deposits) buildup in the arteries supplying blood to the heart muscle. This plaque narrows these arteries, reducing blood flow and causing chest pain (angina), shortness of breath, and potentially a heart attack.
- Heart attack (myocardial infarction): A heart attack happens when blood flow to part of the heart is completely blocked, usually by a blood clot in a narrowed artery. Heart tissues begin to die without enough oxygen. This is a medical emergency.
- Stroke: A stroke occurs when blood flow to part of the brain is interrupted, either due to a blockage (ischemic stroke) or a bleed (hemorrhagic stroke). Symptoms can include sudden weakness or numbness, trouble speaking, vision problems, and severe headache. Time is of the essence in a stroke, just like with a heart attack.
- Heart failure: Heart failure doesn't mean the heart has stopped working. Instead, it means the heart isn't pumping blood as efficiently as it should. This can lead to shortness of breath, fatigue, and swelling in the legs and ankles.
- Arrhythmias: These are irregular heartbeats caused by problems with the electrical signals controlling the heart's rhythm. Some are harmless, while others can be life-threatening.
- Congenital heart defects: These are heart problems present at birth. Some are minor, while others require immediate medical attention.
What causes cardiovascular disease? Many factors contribute to your risk, including:
- High blood pressure (hypertension): This puts extra strain on your heart and blood vessels.
- High cholesterol: High levels of "bad" cholesterol (LDL) contribute to plaque buildup in the arteries.
- Diabetes: High blood sugar damages blood vessels and increases the risk of CVD.
- Smoking: Smoking severely damages the heart and blood vessels.
- Obesity: Being overweight or obese increases the risk of many health problems, including CVD.
- Physical inactivity: A sedentary lifestyle contributes to many risk factors for CVD, including obesity and high blood pressure.
- Family history: A family history of CVD increases your risk.
- Stress: Chronic stress puts extra strain on the body.
- Poor Diet: A diet high in saturated and trans fats increases your risk of high cholesterol.
How can I reduce my risk of cardiovascular disease?
Many lifestyle choices can dramatically reduce your risk.
- Eat a healthy diet: Focus on fruits, vegetables, whole grains, and lean proteins. Cut back on saturated and trans fats, sodium, and added sugars.
- Get regular exercise: Aim for at least 150 minutes of moderate-intensity aerobic activity per week.
- Maintain a healthy weight: Losing even a small amount of weight can make a significant difference.
- Don't smoke: Quit smoking.
- Manage stress: Find healthy ways to cope with stress, such as exercise, yoga, or meditation.
- Get regular checkups: See your doctor to monitor your blood pressure, cholesterol, and blood sugar levels.
Take control of your heart health. Talk to your doctor if you have questions or concerns about your risk of cardiovascular disease.
