Somewhat misleading since more than half of those studied were smoking and vaping. From the study:

Among the 9,352 current and former e-cigarette users, 333 (3.6 percent) had experienced a heart attack at some point, with the highest percentage (6.1 percent) among those who used e-cigarettes daily. In the analysis, a quarter of the 2,259 people who currently used e-cigarettes were former smokers of conventional cigarettes and about 66 percent of current e-cigarette users were also current cigarette smokers.
