title: Impact of climate conditions on hospital admissions for subcategories of cardiovascular diseases.
abstract: BACKGROUND
  The aim of this study has been to examine the association between climate conditions (CC) and hospital admissions for the subcategories of cardiovascular diseases (CVD), according to patients' age.
  
  
  METHODS
  From January 2010 through December 2011, the daily number of hospital admissions for angina pectoris (AP), essential hypertension (EH), acute myocardial infarction (AMI) and ischemic heart diseases (IHD) for adults (19-64 years old) and the elderly (≥ 65 years old), as well as for the CC (N = 728 days) was collected for multivariate Poisson regression analysis, confounding with season and weekends. The results were expressed by using the relative risk with the corresponding 95% confidence interval.
  
  
  RESULTS
  The risk for the AMI among the adults and the elderly is significantly higher for 41.8% and 38.9%, respectively on the days with lower ambient temperature and lesser for 32.7% and 29.8%, respectively on the days with lower air pressure values. The risk for the IHD among the elderly is significantly higher on the days with lower ambient temperature and lower relative humidity for 50.6% and 37.4%, respectively.
  
  
  CONCLUSIONS
  Our findings explain how the CC and subcategories of CVD are associated, which could be used for adequate public awareness of the risk for hospitalization due to climate conditions. Med Pr 2017;68(2):189-197.
