Overview
- UMass Memorial reported eight STEMI heart attacks in 24 hours after the storm, with snow shoveling cited as the trigger in seven cases.
- The American Heart Association cautioned that shoveling in extreme cold can lead to heart attack or sudden cardiac arrest, especially for people with cardiovascular disease or major risk factors.
- Cardiologists note that arm-dominant effort, breath-holding while lifting, and cold-induced vessel constriction drive sharp surges in heart rate and blood pressure to stress-test thresholds.
- Those at elevated risk are urged to avoid shoveling, while others should pace their efforts, push instead of lift, take frequent breaks, warm up, and use a snow blower if available.
- Doctors advise immediate care for chest pressure, shortness of breath, or lightheadedness, warning that events can occur during exertion or up to a week later and can be riskier where EMS response is delayed.
