Smoking habit in relation to coronary heart disease in a group of workers

U skupini od 998 muških ispitanika u dobi života od 40 do 59 godina, zaposlen·ih u nekoliko industrijskih poduzeća, analiziran je odnos između navike pušenja i subjektivnih simptoma, odnosno elektrokardiograma u mirovanju koji upućuju na koronarnu srčanu bolest. Nije utvrđena statistički bitna razlika između nepušača, odnosno pojedinih kategorija pušača, i učestalosti simptoma, kao i EKG-nalaza relevantnih za koronarnu srčanu bolest.In a group of 998 male industrial workers aged 40-59 subjective symptoms of coronary heart disease and electrocardiograms at rest indicative of the disease were studied in relation to the smoking habit.
