Cold exposure increases blood pressure and cardiac work, potentially harming individuals with ischaemic heart disease (IHD). While healthy individuals are unaffected, cold stress can rarely trigger coronary artery spasm and myocardial infarction in those with IHD.

Area of Science:

  • Cardiology
  • Environmental Medicine
  • Physiology

Background:

  • Cold exposure induces physiological responses like vasoconstriction and tachycardia, increasing blood pressure and cardiac workload.
  • Epidemiological data indicates a correlation between ambient temperature and ischaemic heart disease (IHD) mortality, with increased deaths in winter and during heat waves.

Purpose of the Study:

  • To investigate the cardiovascular effects of cold exposure, particularly on coronary blood flow and the potential for coronary artery spasm.
  • To differentiate the impact of cold stress on individuals with normal cardiovascular function versus those with IHD.

Main Methods:

  • Cold stress tests were administered to assess physiological responses.
  • Coronary blood flow and the occurrence of coronary artery spasm were monitored in subjects with and without IHD.

Main Results:

  • Healthy individuals and those with angina but normal coronary arteries showed no adverse effects or coronary artery spasm during cold tests.
  • Patients with IHD exhibited decreased coronary blood flow, and a subset experienced coronary artery spasm, chest pain, and myocardial infarction.

Conclusions:

  • Individuals with normal cardiovascular function tolerate cold stress well.
  • Cold exposure poses a rare but significant risk for individuals with IHD, potentially leading to serious cardiac events, especially during physical exertion.
