Cardiovascular Disease: Types, Causes, Symptoms & Prevention Strategies

CVDs, or cardiovascular diseases, are a group of conditions of the blood arteries and heart. These conditions are the leading cause of death worldwide, contributing to nearly 17.9 million deaths every year. CVDs include, among many ailments, coronary artery disease, cerebrovascular disease, rheumatic heart disease, and others.

However, many remain unaware of its early signs until serious complications arise.

This guide explores what is cardiovascular disease, its different types, causes, risk factors, symptoms, and possible prevention and management. Keep reading for an in-depth analysis.

What are the Types of Cardiovascular Diseases?

• Coronary artery disease (CAD) results from plaque formation, narrowing or occluding the coronary arteries,  reducing blood flow to the heart muscle. It can cause heart attacks or chest discomfort (angina).
• Cerebrovascular disease is a disorder of the blood arteries providing the brain, such as stroke, which might arise from blockage or bleeding in the brain.
• Peripheral arterial disease (PAD) is when blood vessels in the legs narrow, usually causing discomfort and mobility problems.
• Rheumatic heart disease is damage to cardiac valves and muscles caused by rheumatic fever, usually following streptococcal infections.
• Structural heart defects arising from birth are congenital heart diseases.
• Blood clots in the deep veins of deep vein thrombosis can dislodge and block blood flow to the lungs.

What Causes Cardiovascular Disease and Who is at Risk?

CVDs are caused by several different things:

• Unhealthy Diet: It consists of high levels of salt, sugar, saturated fats, and trans fats, all of which can raise the risk.
• Physical Inactivity: One primary risk factor is a lack of regular activity.
• Tobacco Use:Smoking or exposure to secondhand smoke significantly raises the risk.
• Harmful Use of Alcohol:Excessive alcohol consumption can cause several cardiac disorders.
• Obesity:Carrying excess body weight is associated with increased cardiovascular disease risk.
• High blood pressure (hypertension): This puts continuous stress on the heart and arteries, raising the risk of cardiovascular complications.
• High Cholesterol Levels:It can cause LDL cholesterol to accumulate in the arteries.
• Diabetes: Diabetes can harm blood arteries by causing high sugar levels in the blood.
• Air Pollution:Exposure to contaminated air raises CVD risk.
• Genetic Factors: Heart disease in the family can increase vulnerability to cardiovascular diseases.

What are the Symptoms of Cardiovascular Disease?

Although Symptoms of CVD differ depending on the specific condition, they may include:

• Chest Pain or Discomfort:Often described as pressure, tightness, or squeezing.
• Shortness of Breath:Particularly during physical activity or at rest.
• Pain in the Neck, Jaw, Throat, Upper Abdomen, or Back:These areas can be affected during heart events
• Pain, Numbness, Weakness, or Coldness in the Legs or Arms:If the blood vessels in those areas are narrowed.
• Fatigue: Unusual tiredness could indicate heart failure.

It's important to note that some people might not show obvious symptoms at all until a major event, such as a heart attack or stroke, happens.

How can Cardiovascular Disease be Prevented and Managed?

Managing CVD needs both medical treatments and lifestyle modifications when required:

• Prioritize meals rich in fruits, vegetables, whole grains, lean sources of proteins, and healthy fats.
• Engage in physical exercise for at least 150 minutes weekly at a moderate intensity level.
• Quit smoking and avoid secondhand smoke.
• Limit alcohol use, if at all, and drink sensibly.
• Regular health checks cover blood pressure, cholesterol levels, and blood sugar.
• To manage problems, including diabetes, high cholesterol, or hypertension, as directed.
   

Reducing the risk of major consequences linked with cardiovascular illnesses depends much on early identification and intervention.

How is Cardiovascular Disease Treated?

Depending on the cause, symptoms, and type of cardiovascular disease, individuals' treatment may vary. However, some common treatments for this disease are listed below:

1. Lifestyle and home remedies: It is one of the most essential parts of heart disease treatment. Primarily, these include following a healthy diet, exercising regularly, getting proper sleep, quitting smoking and avoiding tobacco products, etc. Doing so can keep your heart healthy and reduce the risk of complications.
2. Medications: Sometimes, to control heart disease symptoms and prevent further complications, your doctor may prescribe some medicines. These medicines depend upon the type of heart disease and its symptoms or complications.
3. Surgery or other Procedures: In circumstances where medicines are not effective, your doctor may recommend some other procedures or surgeries, such as angioplasty, bypass surgery, etc, to treat your cardiovascular disease.
4. Cardiac rehabilitation: Individuals may require personalised exercise training sessions or educational sessions about different ways to keep their heart healthy through a healthy lifestyle.
5. Schedule regular health checkups. Individuals may need to schedule regular health checkups with their healthcare professionals, as they can help ensure that they're properly managing their heart disease.

Cardiovascular illnesses are a significant global health concern that affects millions of people and often advance quietly until a major event, such as a heart attack or stroke, happens. Still, most cardiovascular diseases are avoidable through persistent lifestyle modifications, including regular exercise, a wholesome diet, and abstinence from tobacco.

Early detection and prompt medical treatment can greatly lower the consequences and improve the quality of life. Combating the growing CVDs depends mostly on general awareness and education.
