Valvular diseases affect the heart’s valves, leading to stenosis or regurgitation, disrupting normal blood flow. Common conditions include aortic stenosis, mitral regurgitation, and infective endocarditis. Symptoms include breathlessness, fatigue, and chest pain. Diagnosis relies on echocardiography to determine severity and treatment needs. Management ranges from medications for symptom relief to valve repair or replacement via open-heart or transcatheter techniques, improving heart function and patient outcomes with early intervention.

Cardiac rehabilitation is a medically supervised program designed to improve heart health after a cardiac event such as a heart attack, surgery, or heart failure diagnosis. It includes structured exercise training, lifestyle modifications, dietary counseling, and psychological support to enhance recovery and prevent future complications. Patients receive education on risk factor management, including smoking cessation, weight control, and stress reduction. Rehabilitation programs are tailored to individual needs, improving cardiovascular fitness, reducing symptoms, and enhancing overall quality of life. Regular monitoring and gradual progress help patients regain confidence and resume daily activities while lowering the risk of further cardiac issues.

Cardiovascular imaging and diagnostics play a crucial role in detecting and evaluating heart diseases. Techniques such as echocardiography, cardiac MRI, CT angiography, and nuclear imaging provide detailed heart structure and function assessments. Electrocardiograms (ECG) and stress tests help detect arrhythmias and ischemic heart conditions. These tools aid in diagnosing coronary artery disease, heart failure, valvular disorders, and congenital abnormalities. Advanced imaging ensures early detection, guiding treatment decisions and monitoring disease progression. Non-invasive techniques improve patient safety, while innovations in imaging technology enhance diagnostic accuracy, leading to better clinical outcomes and personalized management of cardiovascular conditions.

Sports cardiology and exercise physiology focus on heart health in athletes and individuals engaging in physical activity. It involves assessing cardiovascular risks, optimizing performance, and preventing sudden cardiac events. Screening includes electrocardiograms, echocardiography, and stress testing to detect underlying conditions like hypertrophic cardiomyopathy or arrhythmias. Exercise physiology studies how physical activity impacts cardiovascular function, guiding training programs for optimal endurance and recovery. Athletes with heart conditions require tailored exercise plans to ensure safe participation. Advances in sports cardiology help balance performance with heart safety, promoting lifelong cardiovascular health and reducing the risk of exercise-induced cardiac complications.

Obesity is a major risk factor for cardiovascular diseases, increasing the likelihood of hypertension, diabetes, and dyslipidemia. Excess body fat leads to chronic inflammation, insulin resistance, and endothelial dysfunction, contributing to atherosclerosis and heart failure. Obese individuals have a higher risk of stroke, coronary artery disease, and sudden cardiac death. Lifestyle modifications, including a balanced diet, regular exercise, and weight management, are crucial for reducing cardiovascular risks. Medical interventions, such as weight-loss medications and bariatric surgery, may be necessary for severe cases. Preventive measures and early intervention play a key role in improving heart health and overall well-being.

Critical care cardiology focuses on managing life-threatening cardiovascular conditions in intensive care settings. It involves treating acute heart failure, myocardial infarction, cardiogenic shock, and severe arrhythmias. Patients require continuous monitoring, advanced imaging, and interventions like mechanical circulatory support, intra-aortic balloon pumps, and extracorporeal membrane oxygenation (ECMO). Rapid diagnosis and timely treatment are crucial to improving survival rates. Critical care teams use medications such as vasopressors, anticoagulants, and antiarrhythmics to stabilize patients. Multidisciplinary collaboration ensures comprehensive care, addressing underlying conditions while preventing complications. Advances in technology and protocols have significantly improved outcomes in critically ill cardiac patients.

Pericardial diseases affect the pericardium, the protective sac surrounding the heart, leading to conditions like pericarditis, pericardial effusion, and constrictive pericarditis. Acute pericarditis, often caused by viral infections, presents with chest pain, fever, and a pericardial friction rub. Pericardial effusion involves fluid buildup, which can progress to cardiac tamponade, a life-threatening emergency. Constrictive pericarditis results from chronic inflammation, causing pericardial thickening and impaired heart function. Diagnosis relies on echocardiography, ECG, and cardiac MRI. Treatment includes anti-inflammatory medications, drainage procedures, or pericardiectomy in severe cases. Early detection and management are crucial to prevent complications and improve patient outcomes.

Digital cardiology and artificial intelligence (AI) are transforming cardiovascular care through advanced diagnostics, remote monitoring, and predictive analytics.

Advances in transplantation techniques, immunotherapy, and artificial heart technology have significantly improved survival rates, offering patients with end-stage heart failure a new chance at life.

Sudden cardiac arrest (SCA) is a life-threatening condition where the heart unexpectedly stops beating, leading to loss of consciousness and collapse. It is often caused by arrhythmias like ventricular fibrillation, disrupting normal blood flow to the brain and organs. Common risk factors include coronary artery disease, heart failure, and inherited heart disorders. Immediate cardiopulmonary resuscitation (CPR) and defibrillation are critical for survival. Automated external defibrillators (AEDs) in public places improve outcomes by delivering timely shocks. Preventive measures include managing risk factors, medications, and implantable cardioverter-defibrillators (ICDs) for high-risk individuals. Rapid intervention significantly increases survival rates and prevents fatal outcomes.

Pulmonary heart diseases affect the right side of the heart due to lung-related conditions like chronic obstructive pulmonary disease (COPD), pulmonary hypertension, and pulmonary embolism. Chronic lung diseases increase pressure in the pulmonary arteries, forcing the right ventricle to work harder, leading to right heart failure (cor pulmonale). Symptoms include shortness of breath, fatigue, chest discomfort, and leg swelling. Diagnosis involves echocardiography, right heart catheterization, and imaging studies. Treatment focuses on managing underlying lung diseases, oxygen therapy, diuretics, and pulmonary vasodilators. Early detection and appropriate management help prevent heart failure and improve quality of life in affected individuals.
