The Division of Cardiology at Mount Sinai St. Luke’s and Mount Sinai West in Manhattan is renowned for its clinical expertise, academic excellence and innovation in treating cardiovascular disease (CVD) -- the leading cause of death and chronic disease in America. Our board-certified physicians are highly skilled and experienced clinicians who specialize in the prevention, early detection and treatment of all forms of heart disease. Our specialists practice at various sites in different neighborhoods of New York City, including the Upper West Side, West Harlem and East Harlem.
Our multidisciplinary team includes cardiologists, surgeons, radiologists, researchers, nurses and nurse practitioners as well as various other healthcare providers who work together to provide outstanding medical care.
We are dedicated to providing a true partnership with patients and their families as we help them navigate through every aspect of their cardiac care. Diagnostic tests and treatment options are thoroughly discussed with patients during their encounters with our medical staff. We also make all diagnostic and therapeutic decisions jointly with our patients and their referring physicians.
In addition, we are dedicated to the early diagnosis and timely evaluation of cardiac diseases and to a comprehensive reduction of all risk factors for heart disease. After clarifying a diagnosis, we develop an individualized treatment plan to meet our patients’ specific needs. And we focus on helping our patient manage all facets of their cardiac condition and provide them with all the tools necessary to maintain or resume a vibrant lifestyle.
Finally, our mission is to provide access to physicians that are most highly regarded and skilled in their respective fields to treat your most complex cardiovascular problems.
Diseases We Treat
We treat all types of cardiovascular disease, including coronary artery disease, acute cardiac problems, heart failure, arrhythmias and hypertrophic cardiomyopathy.
Coronary Artery Disease (CAD)
CAD, the number one killer of men and women in the US, occurs when plaque deposits gradually narrow or block the coronary arteries -- the vessels that supply oxygen-rich blood to the heart. This degenerative process is called hardening of the arteries or atherosclerosis. In many people, it begins in childhood and develops gradually over a lifetime.
Aggressive treatment of CAD risk factors can retard or prevent heart disease in those who have not yet developed the clinical disease and can beneficially reduce symptoms and promote longevity in those with known heart disease.
Our hospitals treat all of the major risk factors for CAD, including:
- High cholesterol
- High blood pressure
- Physical inactivity
Our hospitals’ specialists in the treatment of these risk factors are highly recognized for their clinical skills and excellence. Our hospitals are also the home of the New York Obesity Nutrition Research Center, a prominent institution, led by Dr. F. Xavier Pi-Sunyer, which effectively reduces overweight and obesity in men and women.
In addition, we offer top-notch prevention expertise, including CVD Prevention Program and the Stroke Prevention Program (led by Dr. Carolyn Brockington) -- as well as a Smoking Cessation Program (led by Dr. Mary O’Sullivan).
Chest Pain and Shortness of Breath
Chest pain and shortness of breath may be indicative of CAD, but they can also be due to many other causes. Patients presenting with these and other symptoms are readily assessed by our team of cardiologists who are skilled at conducting a clinical history and physical examination, including an electrocardiogram, blood tests and, when necessary, a selection from various other cardiac tests. These may include:
- Coronary artery calcium scanning, which can be used to detect heart disease even decades before clinical manifestations may appear
- Coronary CT angiography, which can be used to image the coronary arteries in great detail without the use of invasive techniques
- Cardiac stress tests, including the use of treadmill electrocardiography, nuclear stress testing and stress electrocardiography
Unstable Angina, Heart Attack and Other Acute Cardiac Problems
Our critical care cardiologists, led by Dr. Eyal Herzog, Director of our Cardiac Care Unit (CCU), oversee a highly seasoned multidisciplinary team that provides expert care for critically ill cardiac patients. This team includes dedicated and experienced critical care nurses, attending physicians, cardiology fellows, physician assistants and other professionals. We provide 24-hour around the clock care for all critical cardiac conditions, including:
- Unstable and progressive angina
- Heart attack
- Recovery from sudden cardiac arrest
- Cardiac shock
- Decompensation in heart failure patients
- Hypertensive emergencies
- Aortic dissection
- Complicated and life-threatening arrhythmias
- Pulmonary hypertension
The heart's basic rhythm is a precisely regulated phenomenon that provides maximum efficiency and optimum performance. This dynamic phenomenon changes according to our body’s metabolic needs.
Any condition that affects the structure of the heart muscle or its valves, or alters electrical activity within the heart, is likely to cause an arrhythmia (irregular heartbeat). Arrhythmias may be benign, symptomatic, life threatening or even fatal.
Severe coronary heart disease frequently triggers arrhythmias. Congestive heart failure, cardiomyopathy, heart valve disorders and many other diseases may also cause an irregular heartbeat.
Our specialists perform a variety of invasive and noninvasive procedures to diagnose and understand abnormal heart rhythms. Test results provide important information about an arrhythmia, the risk of serious disease, and the patient’s probable response to treatment.
In addition to diagnostic procedures, we offer various methods to restore the heart's normal, regular rhythm. One of the most effective and frequently used is cardiac ablation. During this procedure, we locate the precise source of an arrhythmia, and then apply radiofrequency energy through a catheter to eradicate the small amount of abnormal heart tissue causing the problem.
Other arrhythmia-related procedures and services our cardiologists provide include implanting cardiac defibrillators, pacemaker insertions and pacemaker and cardiac defibrillator follow-up evaluations.
Congestive heart failure is a progressive condition in which the heart's function gradually deteriorates, resulting in diminished cardiac performance. Heart failure has many causes but most commonly begins when a heart attack or long-standing high blood pressure damages or weakens a person's heart. Consequently, the heart loses its ability to pump blood efficiently. Over time, this condition becomes more severe. Ultimately, the reduction of blood flow to vital organs leads to a variety of symptoms, including shortness of breath, lack of energy and swelling.
Our multidisciplinary Heart Failure Program, headed by Dr. Marrick Kukin, is committed to the aggressive treatment of heart failure and its precipitating causes, as well as improving all phases of a heart failure patient’s quality of life and reducing the risk for cardiac death.
Our treatment program applies leading-edge scientific and clinical advances to benefit each patient and includes such services as:
- Biventricular pacing system implantation
- Case management
- Counseling to assist with lifestyle changes
- Defibrillator implantation
- Diagnostic techniques and technology
- Exercise programs
- Heart transplant evaluations
- Information on clinical studies
- Nutritional assessments
- Patient education and disease management
Hypertrophic Cardiomyopathy (HCM)
Our HCM program is headed by Dr. Bette Kim. HCM is marked by a thickening of the heart muscle. The disease is the most common cause of sudden cardiac death in young athletes and in people under 30.
HCM, however, does not affect everyone the same way. Patients may have shortness of breath, exercise intolerance, chest pressure or pain, fainting or no symptoms at all. Proper therapy begins with an accurate diagnosis. We make the initial diagnosis with echocardiography, a noninvasive imaging technique that focuses sound waves to picture the heart and measure the heart wall thickness. We often perform other follow-up tests to confirm our diagnosis and assess risk.
We base each patient’s treatment on the nature and severity of symptoms, the amount of thickening within the heart and the presence of obstructive or nonobstructive HCM. Patients with an obstruction have a blockage inside the heart that causes this muscle to overwork as it pumps blood throughout the body.
HCM treatment options include medications, surgery or implanting a defibrillator -- a device that shocks the heart back to a normal rhythm if a life-threatening irregular heartbeat occurs.
Procedures We Perform
We perform a wide range of noninvasive and minimally invasive cardiology procedures, which are detailed below.
Our advanced team of cardiac imaging experts is well-known for its leading technical and diagnostic skills, and for its leading research in the field of cardiac imaging. Our echocardiography team is led by Dr. Davendra Mehta. Our nuclear cardiology team is led by Dr. Alan Rozanski and Dr. Gordon Depuey. Our advanced imaging program in coronary calcium scanning, cardiac CT angiography and magnetic resonance imaging is led by a unique multidisciplinary cardiologist-radiologist team.
Echocardiography: Cardiac echocardiography (“echo”) is a noninvasive means of obtaining vital information regarding the size and function of the heart, abnormal thickening of the heart’s muscle walls and the condition of the heart valves. The test, which usually takes 20 to 30 minutes to perform, involves ultrasound technology (the same technology used to assess the status of fetuses in pregnant women).
Stress Echocardiography: Echoes can also be obtained in patients at the conclusion of exercise on a treadmill or during the infusion of medication designed to stimulate the heart. By comparing the wall motion of the heart during stress to that of the heart at rest, cardiologists can detect if abnormalities occur during stress, which if present, signal the presence of underlying coronary artery blockages. A stress echo is an important noninvasive tool for determining a diagnosis and prognosis of heart disease.
Transesophageal Echocardiography: This specialized procedure is used by our experts to obtain extremely clear pictures of the heart and adjacent structures like the aorta. It involves the insertion of a probe into the esophagus, which is adjacent to the heart, thereby bypassing ultrasound interference from structures external to the heart.
Nuclear Stress Testing (Nuclear Cardiology): By injecting patients with a very small amount of radiotracer during exercise or pharmacological stress, we can image the blood flow to the heart using nuclear medicine cameras. The radiotracer is taken up by the heart muscle during stress and is compared to a separate blood flow scan at rest. By comparing the stress and rest scans, cardiologists can tell if patients have blockages in their coronary arteries and asses their severity. This noninvasive test is used to both diagnose CAD in patients with chest pain and to determine the risk for future cardiac events in patients with already known heart disease.
Coronary CT angiography (CCTA): The CCTA is a noninvasive method to assess the coronary arteries that provide blood to your heart. This test is performed with a CT scanner and uses intravenous contrast to highlight the arteries of your heart. The CCTA provides detailed information regarding the extent, severity and composition of coronary artery plaque. This test is often used in patients presenting with chest pain, shortness of breath, heart failure or an inconclusive stress test.
Interventional Cardiac and Vascular Service
For cardiac patients requiring the next level of testing and treatment, we provide a vast range of interventional procedures, from diagnostic evaluations to intricate techniques for the treatment of coronary disease. These procedures include:
- Cardiac catheterization
- Carotid stenting
- Complex coronary intervention
- Coronary angiography
- Coronary stent placement
- Implantation of defibrillators
- Implantation of permanent pacemakers
- Myocardial revascularization
- Peripheral vascular intervention
As a leader in cardiology services, we offer a number of special initiatives and organizations to address cardiovascular disease and the needs of special patient populations, including:
All providers are committed to participating in leading-edge research projects at these institutions, including many nationally funded clinical trials.
The research of our doctors is notable for its breadth and depth. For example, our division members are actively involved in investigations to improve the early detection of CAD and help patients better manage CAD risk factors. Moreover, our physicians are leaders in cardiac technology development and in testing new clinical applications for cardiac imaging. In addition, our team of researchers is also investigating new means for improving the care of patients presenting with acute cardiac conditions, such as unstable angina, myocardial infarction and cardiac shock.
Our division is currently led by Division Chief Jagat Narula, MD, PhD, MACC, world-renowned physician-scientist in cardiovascular medicine and imaging. Our experts span the gamut from the early detection and manifestations of heart disease to the treatment of acute cardiac disease, cardiac arrhythmias and heart failure.
