Patients without hyperuricemia, unlike those with hyperuricemia, had a higher left ventricular ejection fraction, a better renal function, and higher hemoglobin levels, had less frequently diabetes mellitus and atrial fibrillation, and showed better tolerance to treatment with angiotensin‐converting enzyme inhibitors/angiotensin receptor blockers and/or beta‐blockers. This evidence concerns the gene ACE and diabetes mellitus.
