Swedish study reveals a 5-minute home quiz predicting heart attack risk with accuracy similar to blood tests and blood pressure readings.

A Swedish study from the University of Gothenburg reveals a five-minute home quiz that predicts heart attack risk with the same accuracy as blood tests and blood pressure readings. The test identifies 64% of people aged 50-64 with significant coronary atherosclerosis, a condition associated with high cardiovascular disease risk. The study was published in the Journal of the American Heart Association.
