| Family history of SCD | 1.73 | 0.216 | 0.73–4.14 | / | ||
| NSVT | 1.46 | 0.303 | 0.71–2.98 | / | ||

CFVR indicates coronary flow velocity reserve; HR, hazard ratio; LV, left ventricular; LAVI, left atrial volume indexed for body surface area; LVOTG, left ventricular outflow tract gradient; LAD, left anterior descending artery; MR, mitral regurgitation; NSVT, nonsustained ventricular tachycardia; PD, posterior descending coronary artery; and SCD, sudden cardiac death.
