Morbidity and mortality associated with the July 1980 heat wave in St Louis and Kansas City, Mo.

The morbidity and mortality associated with the 1980 heat wave in St Louis and Kansas City, Mo, were assessed retrospectively. Heat-related illness and deaths were identified by review of death certificates and hospital, emergency room, and medical examiners' records in the two cities. Data from the July 1980 heat wave were compared with data from July 1978 and 1979, when there were no heat waves. Deaths from all causes in July 1980 increased by 57% and 64% in St Louis and Kansas City, respectively, but only 10% in the predominantly rural areas of Missouri. About one of every 1,000 residents of the two cities was hospitalized for or died of heat-related illness. Incidence rates (per 100,000) of heatstroke, defined as severe heat illness with documented hyperthermia, were 26.5 and 17.6 for St Louis and Kansas City, respectively. No heatstroke cases occurred in July 1979. Heatstroke rates were ten to 12 times higher for persons aged 65 years or older than for those younger than 65 years. The ratios of age-adjusted heatstroke rates were approximately 3:1 for nonwhite v white persons and about 6:1 for low v high socioeconomic status. Public health preventive measures in future heat waves should be directed toward the urban poor, the elderly, and persons of other-than-white races.

Risk factors for heatstroke. A case-control study.

To identify risk factors associated with heatstroke, a case-control study in St Louis and Kansas City, Mo, was conducted during July and August 1980. Questionnaire data were gathered for 156 persons with heatstroke (severe heat illness with documented hyperthermia) and 462 control subjects matched by age, sex, and neighborhood of residence. A stepwise linear logistic regression procedure was used to identify factors significantly associated with heatstroke. Alcoholism, living on the higher floors of multistory buildings, and using major tranquilizers (phenothiazines, butyrophenones, or thioxanthenes) were factors associated with increased risk. Factors associated with decreased risk were using home air conditioning, spending more time in air-conditioned places, and living in a residence well shaded by trees and shrubs. Being able to care for oneself, characteristically undertaking vigorous physical activity, but reducing such activity during the heat, and taking extra liquid were also associated with decreased risk. Our findings also suggest effective preventive measures. During a heat wave, the greatest attention should be directed toward high-risk groups, and relief efforts should include measures shown to be associated with reduced risk.

Disseminated intravascular coagulation in heat stroke. Response to heparin therapy.

A 14-year-old patient with heat stroke, disseminated intravascular coagulation, central nervous system dysfunction, and renal failure was treated, in addition to conventional therapy, with heparin sodium for seven days. Despite very poor prognostic signs on addmission, the patient survived the acute episode and ultimately progressed to a complete recovery.
