Hello and welcome to HCM.
As a specialist,i feel,your B.P.'s isn't alarmingly high.
Along with cycling,reduce calorie intake,so as to reduce your body weight.
Without reducing body weight below 100 kg,don't consider replacement.
For evaluation of breathlessness,you'll need to do following tests :
1. blood routine,RBS,LFT,creatinine
,chest X-ray and ECG.
2. TMT.( treadmill test ).
According to reports,the physician or cardiologist,may do an echo-scan.
If you've any doubts,send the reports to me,as a direct question.
Dr.Matthew J. Mangat.
