When results were tallied, silent heart attacks were twice as common (22 percent) among older patients as recognized heart attacks (10 percent).
In the JAMA study, 26 percent of patients with diabetes (266 altogether) had silent heart attacks, compared with 11 percent who had clinically recognized heart attacks.
So-called "recognized" heart attacks were identified when signs of heart damage were evident, and the patient's medical record indicated that medical attention had been sought and a diagnosis rendered.
The ability of medical students to recognize heart murmurs is poor (20%), and does not improve with subsequent years of training.
Dogs with recognized heart disease were classified according the ISACHC International Small Animal Cardiac Health Councill) classification scheme as class 1 (asymptomatic) - 13 dogs, class 2 (mild to moderate heart failure) - 13 dogs and class 3 (severe heart failure) - 12 dogs.

The incidence of out-of-hospital cardiac arrest (OHCA) in USA has been estimated at 1.89/1,000 person-years and at 5.98/1,000 person-years in patients with any clinically recognized heart disease [ 1].
Dogs with recognized heart disease were classified according the International Small Animal Cardiac Health Council (ISACHC) classification scheme as class 1 – asymptomatic (1a – no cardiac enlargement, 1b with mild enlargement), class 2 - mild to moderate heart failure, and class 3 - severe heart failure (3a – no hospitalization required, 3b – hospitalization required).
This helps physicians to recognize heart rhythm problems as well as any damage to the heart.
