Research is Essential for Improving Patient Care


Research Experience

Dr. Sudarsana Chakrabarti, a veteran of the healthcare industry, having years of experience making her one of the most well-known faces around. With a fellowship training in Heart Failure and Cardiac Transplantation from Northwestern Memorial Hospital, she has handled many complicated cases in this field. Her leading-edge research redefines her way of providing exceptional care for the patients.

Study Prognostic Value of Tissue Doppler Imaging in Heart Failure with Preserved Ejection Fraction(HFPEF).

Description Retrospective cohort study evaluating if reduced systolic mitral annular tissue velocities predict mortality and hospitalization in patients with HFPEF.

Role Principal Investigator

Responsibilities Designed protocol; submitted IRB; collected and reviewed data; performed statistical analysis; prepared manuscript

Study Creation of database of HFPEF patients at Northwestern Memorial Hospital. Prognostic value of sleep disordered breathing and Cardiopulmonary Stress Testing in HFPEF.

Study Clinical Utilization of Diastolic Stress Testing in routine Stress Echocardiogram

Description Retrospective cohort study to determine exercise capacity in patients utilizing tissue Doppler imaging. This study will help to illustrate which population may benefit from diastolic exercise testing.

Role Research Fellow

Responsibilities Collected and reviewed data.

Study Prognostic Utility of Patient's Clinical Characteristics and myocardial viability assessment in high risk coronary artery bypass grafting surgery.

Description Retrospective cohort study analyzing the outcome of cardiac surgery at Northwestern memorial Hospital by utilizing the Adult Cardiac Surgery Database. We hypothesized that clinical parameters when combined with imaging modalities for detection of myocardial viability (dobutamine stress imaging, cardiac magnetic resonance imaging, nuclear stress testing)predict outcome in cardiac surgery.

Role Principal Investigator

Responsibilities Initiated study, designed protocol; submitted IRB; collected and reviewed data.

Study Nocturnal hypoxemia in patients with suspected obstructive sleep apnea who presented with acute coronary syndrome.

Description Prospective cohort study to assess nocturnal hypoxemia through continuous pulse oximetry (CPOX) in patients with suspected sleep apnea who presented with acute coronary syndrome.

Role Principal Investigator

Responsibilities Initiated study; designed protocol; submitted IRB; enrolled patients; collected and reviewed data; performed analysis using score software.

Study Role of sleep apnea in progression of heart failure in patients on optimal therapy.

Description Retrospective cohort study to assess impact of sleep apnea in prognosis of heart failure using data from UNITE-HF registry (a multi-center heart failure database) to demonstrate the role of treatment of sleep apnea in heart failure patients on optimal therapy.

Role Principal Investigator

Responsibilities Initiated project and created protocol; created and maintained database; analyzed data.

  • Stanford University School of Medicine, California
  • Research Associate, Siba P. Raychaudhuri, MD.

Study Conducted basic research on path physiological aspects of novel drug development in inflammation. I researched about cell trafficking and role of chemokines in acute and chronic inflammation and various different factors within the bloodstream which maintain a balance between pro and anti-inflammatory environments.

Study Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE)

Description NIMH project to determine the long-term effectiveness and tolerability of the newer atypical antipsychotics, relative to one other and in comparision to old antipsychotic agents in schizophrenia.

Role Research Associate

Responsibilities Maintained database; documented patient compliance; conducted structured interviews; obtained certification in Positive and Negative Affect Scale (PANAS) in schizophrenia used in psychiatry; reviewed medical charts to abstract and analyze research data.
