Prognostic Role of B-Type Natriuretic Peptide in Adults with Acute Dyspnea Requiring Emergency Admission.

Objective: The aim of the study was to evaluate the role of B-type natriuretic peptide (BNP) in patients presenting with acute dyspnea admitted in emergency services.

Materials And Methods: A prospective observational study was conducted on 100 patients presenting to the emergency of Dayanand Medical College and Hospital and Hero DMC Heart Institute with acute dyspnea of <48 h duration, in which BNP levels were done on arrival to emergency.

Results: BNP levels were significantly higher in patients having left ventricular dysfunction, both systolic and diastolic.

Seasonal variation in 24 h blood pressure profile in healthy adults- A prospective observational study.

The clinical and experimental data on seasonal variation in blood pressure is mainly from office and home blood pressure (BP) monitoring studies. There are few studies from temperate climates on seasonal changes with ambulatory blood pressure (ABP) monitoring and none from India. This is a prospective, observational study among healthy adults.

Outcome and predictors of cardiopulmonary resuscitation among patients admitted in Medical Intensive Care Unit in North India.

Background: Outcome and predictors of survival after cardiopulmonary resuscitation (CPR) in Intensive Care Units (ICUs) have been extensively studied in western world, but data from developing countries is sparse.

Objectives: To study the outcome and predictors of survival after CPR in a Medical ICU (MICU) of a tertiary level teaching hospital in North India.

Materials And Methods: A 1-year prospective cohort study.

Epidemiology of adult obstructive sleep apnoea syndrome in India.

There is a paucity of published Indian studies on the prevalence and risk factors of obstructive sleep apnoea (OSA) in adults. The limited published literature, however, does not suggest significant differences in the prevalence and risk factors for OSA and obstructive sleep apnoea syndrome (OSAS) as compared to western studies. Well designed studies are required from all parts of India.

Critical care aspects of malaria.

Malaria remains a major health problem in much of Asia and Africa. A steady number of cases of imported malaria are also seen in many countries of the developed world. Plasmodium falciparum malaria and to some extent malaria caused by other species of Plasmodium can lead to many complications such as acute respiratory distress syndrome (ARDS), cerebral malaria, acute renal failure, severe anemia, thrombocytopenia, and bleeding complications.

Effect of antituberculosis treatment on cardiopulmonary responses to exercise in miliary tuberculosis.

Background & Objectives: Tuberculosis (TB) is a major health problem in the developing world. In this preliminary study, we report the effect of antituberculosis treatment (ATT) on cardiopulmonary responses to exercise in patients with miliary tuberculosis (MTB).

Methods: The prospective study of cardiopulmonary responses to exercise in patients with MTB within one month of starting (n=14), on completion of ATT (n=7) and in 15 healthy subjects using the incremental exercise test was performed on a bicycle ergometer.

Outdoor air pollution and emergency room visits at a hospital in Delhi.

Several reports from large metropolitan cities have indicated significant association between acute morbidity and mortality from cardio-respiratory disorders and daily levels of major pollutants in the ambient air. Despite the wide-spread public concern about the adverse health effects of air pollution, there is substantial uncertainty regarding the effects of these pollutants at a concentration typical of Delhi, which is one of the ten most polluted cities in the world and the most polluted city in India. This study was undertaken to correlate the daily levels of various pollutants with the number of patients visiting the All India Institute of Medical Sciences (AIIMS, New Delhi) casualty for aggravation of certain defined cardiorespiratory disorders.
