^aHeart failure deaths in Finland are classified according to the cause underlying heart failure.

^bIncludes valvular disease (n=11), hypertensive heart disease (n=6), endocarditis (n=1) and ‘unspecified disorder of circulatory system’ (n=1).

^cCardiovascular mortality plus stroke and cardiac events.

^dCoronary events, fatal and nonfatal heart failure, pacemaker implantation and other cardiac deaths.

^eMortality from ischemic heart disease and sudden death, and incidence of myocardial infarction and coronary revascularization.

^fFatal and nonfatal strokes. Composite events do not add up since they include only the first event.
