Cardiovascular diseases affect millions of people worldwide, impacting the heart and blood vessels in different ways. Some conditions develop gradually, while others can cause sudden health emergencies. Recognising these diseases and understanding their effects on the body can help individuals take preventive measures and seek timely medical care. Consulting the best cardiologist in Dubai can make a significant difference in managing these conditions effectively.
Coronary artery disease (CAD):
Coronary artery disease occurs when plaque builds up in the arteries, restricting blood flow to the heart. This can lead to chest pain (angina) and increase the risk of heart attacks. CAD often develops due to unhealthy lifestyle habits, high cholesterol, and high blood pressure. Regular check-ups and lifestyle modifications can help manage this condition.
Heart failure:
Heart failure happens when the heart is unable to pump blood efficiently, leading to fatigue, shortness of breath, and fluid buildup in the body. It can result from untreated high blood pressure, CAD, or previous heart attacks. While it is a chronic condition, proper treatment, including medication and lifestyle changes, can improve quality of life.
Arrhythmia (Irregular Heartbeat):
Arrhythmia refers to irregular heartbeats, which can be too fast, too slow, or erratic. Some arrhythmias are harmless, but others may cause dizziness, fainting, or even cardiac arrest. Medical interventions, such as medications, pacemakers, or catheter procedures, help regulate the heartbeat and prevent complications.
Stroke:
A stroke occurs when blood flow to the brain is disrupted, either due to a clot (ischemic stroke) or a ruptured blood vessel (hemorrhagic stroke). This can lead to paralysis, speech difficulties, and cognitive impairment. Quick medical attention is important in minimising long-term damage. Managing blood pressure and avoiding smoking can reduce stroke risk.
Peripheral artery disease (PAD):
PAD affects the blood vessels outside the heart, primarily in the legs, causing reduced circulation. Symptoms include leg pain, numbness, and slow-healing wounds. If untreated, PAD can lead to serious complications, including infections and amputations. Regular exercise and proper medical care can help improve blood flow.
Congenital heart defects:
Congenital heart defects are structural abnormalities present at birth, affecting how the heart functions. Some defects are mild and require minimal intervention, while others may need surgery or long-term medical care. Early detection through prenatal screenings can help manage these conditions effectively.
