[Research progress in the heatstroke-induced myocardial injury]

Area of Science:

• Cardiovascular Physiology
• Environmental Medicine
• Pathology

Background:

• Heat stroke is a severe heat-related illness with high mortality, often due to multiple organ dysfunction syndrome (MODS).
• The cardiovascular system is a primary target of heat injury, experiencing significant dysfunction during heat stroke.
• Existing research indicates heat stress impacts myocardial function, heart rhythm, and blood flow, altering hemodynamic status.

Purpose of the Study:

• To review the pathophysiological and histological changes associated with heatstroke-induced myocardial injury.
• To summarize the clinical manifestations of myocardial damage in heat stroke patients.
• To provide a reference for understanding and researching hyperthermia-induced cardiac damage.

Main Methods:

• Literature review of existing studies on heat stroke and myocardial injury.
• Analysis of pathophysiological mechanisms linking heat stress to cardiac dysfunction.
• Compilation of clinical findings, including electrocardiogram, echocardiography, and biomarker data.

Main Results:

• Heat stress induces myocardial inhibition, conduction abnormalities, and altered blood flow distribution.
• Significant changes in hemodynamic indicators and cardiac biomarkers are observed in heat stroke patients.
• Histological examination reveals myocardial damage consistent with severe heat exposure.

Conclusions:

• Heatstroke-induced myocardial injury is a critical factor contributing to mortality.
• Understanding the cardiac pathophysiology of heat stroke is essential for developing effective treatments.
• Further research is needed to elucidate the complex mechanisms of heat-induced cardiac damage.
