For patients suffering with different types of cardiovascular diseases, the need to understand the pattern of occurrence of the disease in a population is very essential. The goal of the present study was to understand the pattern of occurrence of the various cardiovascular diseases and bring awareness about the rational use of drugs. Total 100 patients suffering with different types of cardiovascular diseases were included in present study within a time period of 6months. It was a prospective randomized study. The tools which were used throughout the study were patient information sheets (case sheets) and questionnaire. As per the data collected from the case sheets of 100 patients it can be concluded that average prevalence of cardiovascular diseases were found to be more in males than in females. Among the various CVD high prevalence was found to be of hypertension. Common age group of CVD is observed as 40 to 60 years. We have concluded that the drugs used for the treatment of cardiac disease are almost found to be rational. Rational use of drugs minimizes poly-pharmacy, drug interactions and in turn it minimizes the hospital stay. The drugs prescribed are from national list of essential medicines. The prescribing habits, route of administration, dosage forms are found to be appropriate.
