Evening everyone, recently diagnosed with left ventricle failure. Completely shocked as very healthy or so I thought. All started due to BP suddenly being 185/125. I've had echocardiogram (which diagnosed problem) and have recently had a myocardial perfusion scan which confirmed problem (40% ejection) stress test results better than expected. My question, cardiologist telling me he feels my heart failure is genectic. But have recently been told by a doctor abroad (went for a fit to dive certificate, which he wouldn't give me) that there is always a reason for sudden heart failure and to seek a second opinion. Is he right!
