The overall goals of Dr. Natarajan's research are to improve cardiovascular disease risk assessment and to optimize care for complex chronic conditions like diabetes and heart failure. .

Dr. Natarajan has analyzed large population-based databases to improve CVD risk assessment and management. He is currently focused on conducting Randomized Clinical Trials (RCT's) to evaluate behavioral interventions.

Behavioral Clinical Trials and Clinical Quality Improvement Projects (please cut and paste the link below in web browser for details)

1) Preventing Amputation by Tailored Risk-based Intervention to Optimize Treatment (PATRIOT):  This 4-year RCT tests the effectiveness the effectiveness of a personalized intervention aimed to improve diet, exercise, medication adherence and self-care in order to prevent incident foot lesions in patients with diabetes (Primary Prevention trial).  Details at:

2) STEP UP to Avert Amputation in Diabetes: This 4-year trial tests the effectiveness of a tailored intervention aimed to improve self-care and self-monitoring in order to prevent the recurrence of foot ulcers in patients with a previous diabetic foot ulcer (Secondary Prevention).  Details at:

3) VIP Treatment in Heart Failure: This interdisciplinary theory-based 3-arm randomized controlled trial (RCT) bases one active arm on the Transtheoretical Model (TTM), while the other active arm adds environmental (human and built) tailoring to TTM with the goals of interest being to enhance medication adherence and improve quality of life.  Details at:

4) VALOR in Heart Failure: This trial evaluates a quality improvement program (QIP) to improve HF care using a pretest-posttest control group design.  The QIP involves a patient-based behavioral and checklist intervention, as well as provider and system-targeted checklists and treatment defaults.  Details at:

5) The SMILE BP Toolkit project, builds on our BP trial to develop and pilot a toolkit and then perform formative evaluation of toolkit implementation.  Details at:

6) TACTICS: This RCT tests the effects of a Transtheoretical model-based intervention and a prospect theory-based intervention in improving low-density lipoprotein cholesterol in adults with diabetes.  Details at:

7) A Behavioral Intervention to Improve Hypertension Control: This 3-arm RCT evaluates whether a telephone-delivered stage-matched behavioral intervention is effective in lowering blood pressure compared to a health education intervention and usual care.  Details at:

For Students: We conduct these research projects in a busy urban hospital setting  with a multidisciplinary group that includes individuals with expertise in medicine, psychology, epidemiology, statistics, health education, public health, and health economics.  There are opportunities for students to obtain research experience through the INSPIRE Internship Program or work with our team as a clinical research volunteer.  Please email or xiao.xiao@nyumc for details.
