Dr Andile Xana, a cardiologist at Mediclinic Heart Hospital, answers frequently asked questions about heart disease.
What is the most common cause of heart disease?
Coronary artery disease (CAD) is the primary cause of heart disease. It occurs when cholesterol and plaque build up in your arteries, leading to atherosclerosis.
What are possible symptoms of heart disease?
Heart disease can manifest through symptoms like angina (chest pain) and complications such as arrhythmias (irregular heartbeat), heart attacks, and heart failure.
What are the risk factors for heart disease?
High blood pressure, high cholesterol, and smoking are key risk factors. Adopting a heart-healthy lifestyle, including a balanced diet, regular exercise and stopping smoking can significantly reduce these risks.
How can I maintain a heart-healthy lifestyle?
Work with a healthcare professional to follow a heart-healthy diet; do regular physical activity; control your weight; manage blood pressure (BP); and monitor your cholesterol levels.
Is it safe to have sex after heart surgery or a cardiac event?
Yes, sexual intimacy is an essential part of wellbeing. Consult your healthcare provider for guidance. Avoid heavy meals and excessive alcohol before sex. If you experience angina during sex, follow your health professional’s instructions and seek immediate help if symptoms persist.
What are the benefits of physical activity for heart health?
Physical activity is crucial for cardiovascular health. It can lower blood pressure, cholesterol, and blood sugar, control weight, improve heart and lung function, and reduce the risk of blood clots. Aim for at least 150 minutes of aerobic activity weekly, complemented by strength-building exercises.
How can I monitor my heart health during physical activity?
Always consult a healthcare professional before starting a new activity programme. Use tools like heart rate monitors and blood pressure measurements as medically recommended. Ensure your exercise routine challenges you enough to elevate heart rate and breathing.
You can help avoid or manage the risk of heart disease by adopting a lifestyle that promotes heart health, staying well informed, and working closely with healthcare professionals. Doing these things is the best way to face the challenges of heart disease and lead a satisfying and heart-conscious life.
