Brief Biography:

As a practicing Family Medicine physician for over 30 years (both in India and here in the United States), Dr. Gupta has developed a keen interest in primary prevention of disease. He has been focusing upon preclinical precursors (prediabetes and prehypertension) for the most common chronic diseases (diabetes mellitus and hypertension).

 

With the use of non-invasive 7-day automatic ambulatory blood pressure monitoring he has discovered that prediabetes is associated with circadian blood pressure variability abnormalities. He has also found that otherwise healthy obese subjects that had normal fasting serum glucose and mild elevation of systemic inflammation had normal circadian blood pressure variability and endothelial function, while those healthy obese that had prediabetes (fasting serum glucose 100-125 mg/dL) and a significantly exacerbated systemic inflammation, had abnormal circadian blood pressure variability and endothelial dysfunction. He has elucidated the prevalence of prediabetes (26.8%), prehypertension (36.3%) and co-existing prediabetes and prehypertension (11.2%) in healthy adult population (NHANES 1999-2006) in the United States.

 

That means that one in three healthy adults has prehypertension, one in four has prediabetes and one in ten has both prehypertension and prediabetes. Over 30% of individuals with prehypertension deteriorate into hypertension, while about 20% of healthy adults with prediabetes are diagnosed with diabetes in 4 years.

 

Given the high prevalence of these pre-disease states, which are also associated with an increased risk for accelerated adverse cardiovascular events, urgent preventive measures to combat high conversion rates from pre-disease to overt chronic disease conditions are required.

 

He has also recently shown that high-glycemic high-fat diet in rats increases fasting blood sugar and also results in abnormal blood pressure variability. He was also able to show this to occur in human volunteers: who along with the weight gain with a mere 8 weeks of overfeeding, showed an increase in waist circumference (“bad central fat”), fasting glucose (prediabetes) and resting blood pressure (prehypertension). These volunteers, in addition to this, compared to their own pre-overfeeding circadian blood pressure variability and resting endothelial function, did exhibit significant abnormalities of circadian blood pressure variability and resting endothelial function. 

 

With the use of novel, non-invasive methodologies (automatic 7-day ambulatory blood pressure monitoring and resting endothelial function testing) in healthy high risk individuals he is working to establish a cause and effect relationship between prediabetes (central adiposity, exacerbated systemic inflammation, dyslipidemia and elevated cardiac risk ratios) and circadian blood pressure and endothelial function abnormalities. This will help with the first steps in the design of meaningful preventive measures for primary prevention of chronic disease.

Personal Statement

As a practicing Family Medicine physician for over 30 years (both inIndiaand here in theUnited States), I have developed a keen interest in primary prevention of disease. I have been focusing upon preclinical precursors (prediabetes, prehypertension) for the most common chronic diseases (diabetes mellitus and hypertension). With the use of non-invasive 7-day automatic ambulatory blood pressure monitoring we discovered that prediabetes is associated with circadian blood pressure variability abnormalities. We also found that otherwise healthy obese subjects that had normal fasting serum glucose (and mild elevation of systemic inflammation) had normal circadian blood pressure variability and endothelial function, while those healthy obese that had prediabetes (fasting serum glucose 100-125 mg/dL) and a significantly exacerbated systemic inflammation, had abnormal circadian blood pressure variability and endothelial dysfunction. We have elucidated the prevalence of prediabetes (26.8%), prehypertension (36.3%) and co-existing prediabetes and prehypertension (11.2%) in healthy adult population (NHANES 1999-2006) in theUnited States. Given the high prevalence of these pre-disease states, which are also associated with an increased risk for accelerated adverse cardiovascular events, urgent preventive measures to combat high conversion rates from pre-disease to overt chronic disease conditions are required. This study with the use novel, non-invasive methodologies (automatic 7-day ambulatory blood pressure monitoring and resting endothelial function) in healthy high risk individuals will help establish a cause and effect relationship between prediabetes (central adiposity, exacerbated systemic inflammation, dyslipidemia and elevated cardiac risk ratios) and circadian blood pressure and endothelial function abnormalities. This will help with the first steps in the design of meaningful preventive measures for primary prevention of chronic disease.

What I think of the idea behind WebmedCentral:

I think that this it is an excellent idea. It would help promote scientific knowledge in an unencumbered fashion.
