Implication

Randomized trial examines cardiac strain during exercise in adults with or without coronary artery disease, suggesting safety limits for physical activity in heat.

Key Points

The study aims to identify ambient air temperature thresholds that increase cardiac strain during moderate exercise in individuals with or without coronary artery disease.
Eighteen adults with CAD and eighteen adults without CAD completed five treadmill walks at varying temperatures (18°C, 27°C, 30°C, 35°C, 40°C).
The study used a randomized cross-over design with fixed humidity conditions for all sessions.
Measurements included heart rate, rectal temperature, mean skin temperature, and blood pressure, with data analyzed using repeated-measures ANOVA.
Heart rate significantly increased at 35°C (18 bpm; p < 0.001) and at 40°C (25 bpm; p < 0.001) compared to 18°C.
Rectal and mean skin temperatures also rose significantly at 30°C, 35°C, and 40°C compared to 18°C.
Diastolic blood pressure was lower at 40°C (-7 mmHg; p = 0.005).
