Your active father?s heart pumping capacity (LVEF 57%) is completely normal. The thickened heart wall (concentric LVH) and mild stiffness (grade 1 diastolic dysfunction) are common with aging and can indeed explain his intermittent shortness of breath, as a stiffer heart requires more effort to relax and fill with blood. Regarding his medications, Contiflo D (tamsulosin/dutasteride) and Zurig 40 (febuxostat) are unlikely to directly cause this, though tamsulosin can sometimes cause minor fluid retention or nasal congestion. I gently recommend sharing these results with his doctor or cardiologist to review his blood pressure and ensure he remains safely active.
