Understanding Heart Attacks: Causes, Warning Signs, Risk Factors and How to Protect Your Heart

The most common cause of a heart attack is a blockage in one of the coronary arteries that supply blood to the heart muscle. A buildup of fatty deposits, known as plaque, can narrow the arteries over time. If a plaque ruptures, a blood clot can form and significantly restrict blood flow to the heart. Several lifestyle factors and medical conditions can increase the risk of this happening.

1. High Blood Pressure Long-term uncontrolled hypertension can damage the walls of blood vessels and increase the strain placed on the heart. Regular blood-pressure monitoring and appropriate treatment can help reduce cardiovascular risk. 2. High Cholesterol High levels of LDL cholesterol can contribute to plaque buildup inside the arteries. Over time, this can narrow the coronary arteries and increase the risk of heart disease and heart attack. A lipid profile can help assess cholesterol levels. 3. Diabetes Diabetes can affect blood vessels and increase the risk of cardiovascular disease. People with diabetes should work with their healthcare professionals to maintain appropriate blood glucose levels and manage other cardiovascular risk factors. 4. Smoking and Tobacco Use Smoking damages blood vessels and increases cardiovascular risk. Avoiding tobacco is one of the most important steps you can take to protect your heart. 5. Physical Inactivity A sedentary lifestyle can contribute to obesity, high blood pressure, diabetes and abnormal cholesterol levels all of which can increase cardiovascular risk. Regular physical activity appropriate for your health and fitness level can support cardiovascular health. 6. Unhealthy Diet A diet high in sodium, saturated fats, trans fats and highly processed foods can contribute to cardiovascular risk. A heart-healthy eating pattern should emphasize vegetables, fruits, whole grains, legumes, appropriate sources of protein and other nutrient-dense foods. 7. Chronic Stress Persistent psychological stress may contribute to unhealthy behaviours and can be associated with cardiovascular risk. Managing stress through healthy lifestyle habits and professional support when needed can be beneficial. 8. Inadequate Sleep Poor or insufficient sleep can be associated with cardiovascular risk and may also affect blood pressure, metabolism and overall health. Aim for a consistent sleep schedule and seek medical advice if you regularly experience significant sleep problems. 9. Family History Having close relatives with cardiovascular disease can increase your risk. If you have a strong family history of heart disease, discuss appropriate screening and preventive measures with a healthcare professional. 10. Age and Other Medical Conditions The risk of cardiovascular disease generally increases with age. Other conditions, including obesity, kidney disease and certain metabolic disorders, can also contribute to cardiovascular risk.

Recognizing heart attack symptoms is extremely important because early treatment can be critical. Common warning signs can include:

• Pressure, squeezing, heaviness or discomfort in the chest
• Pain or discomfort that may spread to the arm, shoulder, back, neck or jaw
• Shortness of breath
• Cold sweating
• Nausea or vomiting
• Unusual weakness or fatigue
• Dizziness or light-headedness

Symptoms can vary between individuals. Some people, particularly women, older adults and people with diabetes, may experience less typical symptoms. When should you seek emergency medical help? If you or someone around you develops symptoms that could indicate a heart attack, seek emergency medical care immediately rather than waiting for the symptoms to disappear. Do not attempt to diagnose a heart attack yourself.

You cannot eliminate every cardiovascular risk factor, but many important risks can be addressed through lifestyle changes and appropriate medical care.

Regular monitoring can help identify risk factors before they become more serious. Depending on your age, medical history and risk profile, your doctor may recommend monitoring:

• Blood pressure
• Blood glucose
• Cholesterol and lipid profile
• Body weight and BMI
• Other cardiovascular risk factors

If you have existing medical conditions, follow your doctor's recommended monitoring and treatment plan.

Focus on a balanced diet containing:

• Vegetables and fruits
• Whole grains
• Pulses and legumes
• Appropriate protein sources
• Healthy fats in suitable amounts

Limit excessive:

• Salt
• Saturated fats
• Trans fats
• Highly processed foods
• Added sugars

If you have diabetes, high cholesterol or hypertension, your dietary requirements may be different. Consider getting individualized advice from a qualified healthcare professional or dietitian.

Regular physical activity can support cardiovascular fitness and help manage body weight, blood pressure, blood sugar and cholesterol. The appropriate amount and intensity of exercise depend on your age, health status and existing medical conditions. If you already have heart disease or symptoms such as chest pain or unusual breathlessness, speak with your doctor before beginning a new exercise programme.

There is no safe level of tobacco exposure for cardiovascular health. Quitting smoking can substantially reduce cardiovascular risk over time. If you need help quitting, speak with a healthcare professional about appropriate cessation support.

Don't ignore conditions such as:

• Diabetes
• High blood pressure
• High cholesterol

These conditions can often be managed effectively with lifestyle changes, regular monitoring and medications when prescribed. Do not stop or change prescribed medication without consulting your doctor.

Excess body weight can increase the risk of conditions associated with cardiovascular disease, including hypertension, diabetes and abnormal cholesterol. A sustainable approach combining appropriate nutrition, physical activity and medical guidance is generally preferable to extreme diets.

A cardiovascular evaluation may be appropriate if you have:

• A family history of heart disease
• Diabetes
• High blood pressure
• High cholesterol
• Obesity
• Smoking history
• Previous heart disease
• Reduced physical activity
• Recurrent chest discomfort or breathlessness

Your doctor can determine which tests or evaluations are appropriate based on your individual risk factors.
