About the department

The department of cardiology at Memorial Sisli Hospital Istanbul offers a full range of medical services for the prevention, diagnosis and conservative treatment of heart disease. The department's medical team successfully uses effective pharmacotherapy regimens in their clinical practice and modern interventional techniques that allow restoring the normal state of the cardiovascular system and avoiding more invasive heart surgeries. The department includes an advanced chest pain unit that provides round-the-clock medical care to patients with the acute coronary syndrome. The department also has a heart attack centre fully equipped with the latest technological devices, angiography rooms, operating rooms and intensive care units. For complex treatment, cardiologists work closely with specialists from the departments of cardiac and vascular surgery, radiology and nuclear medicine.

The department's therapeutic options include treating arrhythmias with pacemakers and catheter ablation. The medical team uses only effective and modern methods of treatment. One of the essential innovations of the department is enhanced external counter-pulsation (EECP), which is used to treat coronary heart disease and heart failure. In addition, the extensive experience of cardiologists allows them to treat patients with valvular diseases, rheumatic heart diseases, cardiomyopathies and vascular diseases.
