Excluding patients with PAH, LVH, LVEF ⩽45%, aortic stenosis, aortic or mitral insufficiency ⩾ grade III, patients with a blood pressure ⩾140/85 mmHg and patients receiving antihypertensive drugs except for calcium channel blockers. Values are mean (SD) unless indicated otherwise. Statistical tests: χ2 test or Fisher’s exact test, as appropriate, to compare mitral flow patterns for categorical variables.
