Abstract

This is a prospective and comparative study over four months between the cold season (January-February) and the hot season (April-May) 2016. It concerned 258 patients hospitalized in the medicine-cardiology department during this period in whom the diagnosis of cardiovascular pathologies has been made. Through this work, we have studied the epidemiological, clinical, paraclinical, therapeutic, evolutionary aspects and finally the impact of climatic and seasonal variations on cardiovascular pathologies. Epidemiologically, cardiovascular pathologies account for 55.60% of admissions to the department. We note a male predominance with 53.10% against 46.90% for the female sex. The average age was 55.17 years. The age group over 60 years is the most affected with 54.25%. The cardiovascular disease admission rate was 43.41% in the cold season compared to 56.59% in the hot season. Clinically, the most frequent diagnoses were heart failure, stroke and hypertension with 47.28%, respectively; 24.03%; and 8.91%. From a therapeutic standpoint, the protocol used is largely based on diuretics, CE inhibitors and antiplatelet agents. From an evolutionary standpoint, the course is favorable in 81.79% of patients. The death rate is 14.34% with a peak of deaths during the hot season. Thus we found 24 deaths, a mortality rate of 16.43% and 64.86% of total deaths in the hot season. Indeed, the temperature rises lead to an increase in admissions but also in mortality linked to cardiovascular diseases.
