Hi Sir, I am 32 year old male, I went for general health check up today. 2d echo report says Grade 1 LV Diastolic Dysfunction and sinus Tachycardia.. Normal Values and Chambers, No LV RWMA, trival MR+/TR+, Normal LV/RV systolic function, No P.E/Clot/Vegetation.. My ecg pulse before thread mill test is 114 & BP is 110/70. After thread mill test pulse is 136. Bp is 130/80. LVEf - 62%.  TSH - 1.73 MIU/L, HBA1C test - 5.4%, fasting sugar - 107 mg/dl. Ultra sound is no obvious abnormalities seen. Went to Cardiologist he is saying reports are okay..  No need to worry about grade 1 LV Diastolic Dysfunction and not even suggested any medication.. Is this a serious issue which causes any issues in future to me ????? Please see attached reports and provide your suggestions.. Till now I don't have BP, dibeties, heart.. I am not a smoker and not alocholic..
