Temperature fluctuation and acute myocardial infarction in Beijing: an extended analysis of temperature ranges and differences.

ABSTRACT:

Purpose

Few studies examined the relationship between temperature fluctuation metrics and acute myocardial infarction (AMI) hospitalizations within a single cohort. We aimed to expand knowledge on two basic measures: temperature range and difference.

Methods

We conducted a time-series analysis on the correlations between temperature range (TR), daily mean temperature differences (DTDmean), and daily mean-maximum/minimum temperature differences (TDmax/min) and AMI hospitalizations, using data between 2013 and 2016 in Beijing, China. The effects of TR_n and DTDmean_n over n-day intervals were compared, respectively. Subgroup analysis by age and sex was performed.

Results

A total of 81,029 AMI hospitalizations were included. TR₁, TDmax, and
