We investigated decadal (2010–2019) cardiovascular, cerebrovascular, and respiratory mortality sensitivity to annual warm temperatures in major Japanese cities: Sapporo, Tokyo (23 wards), and Osaka. The summer mortalities (June–August) increased with the monthly mean temperature for acute myocardial infarction, other acute ischemic heart diseases, cerebral infarction, and pneumonia in the three cities. Monthly mean temperatures were an indicator of these disease mortalities in Japan. However, similar responses were not found for cardiac arrhythmia and heart failure (excluding Sapporo), subarachnoid hemorrhage, and intracerebral hemorrhage. The decadal sensitivities and risk ratios between the maximum and minimum monthly mean temperatures were calculated using a linear regression model. In Sapporo, Tokyo, and Osaka, for example, the analyses of acute myocardial infarction showed summer positive responses of 0.19–0.25, 0.13–0.18, and 0.12–0.30, respectively, as the mortality rate (per 100,000 population) per 1 °C of monthly mean temperature, which estimated increased risks (between the coolest and hottest months) of 37–65% in Sapporo, 31–42% in Tokyo, and 35–39% in Osaka.

Abstract OBJECTIVE To analyze the ranking and percentage variation of the main causes of hospital admissions and death of Brazilian elders between 2005 and 2015, according to gender and age groups. METHOD Retrospective and temporal analysis study. The six main causes of hospitalization and death of elders were collected in DATASUS according to sex and age groups (60 ~ 79, ≥80) in 2017. RESULTS Heart Failure (2005) and pneumonia (2015) were the two main causes of hospital admissions in both sexes and age groups, except for the younger group. Acute Myocardial Infarction was the main cause of death in 2005 and 2015. The second cause in the overall ranking was the Stroke in 2005 and Pneumonia in 2015. CONCLUSION Circulatory and respiratory diseases were the main causes of hospital admissions and death among the elderly, highlighting the impotant increase in pneumonia as a cause of morbimortality.

Heart failure - severe, common clinical syndrome that is the result of many heart diseases is progressive, significantly reduces the life expectancy of patients and impairs its quality. Leading nosological forms the structure of coronary heart disease for many years, is a myocardial infarction. Growing proportion of elderly in most populations, increased survival after acute myocardial infarction (AMI) resulted in a significant increase in the number of patients with chronic heart failure (CHF). Increased tone of the sympathetic division precedes the development of chronic cerebral ischemia and, therefore, may complicate the course of disease in the presence of chronic heart failure.
