Heart failure & cardiomyopathies
Impact of Global Warming on Weight in Patients with Heart Failure During the 2019 Heatwave in France
Authors' conclusion
The relationship between temperature and weight is very strong (P < 10-7 ). The magnitude of the effect seems clinically relevant with a variation of 1.5 kg during a short period.
