I just turned 31 years old and found out I have hypertensive heart disease stage 2. The symptoms I've been feeling are swollen feet and ankles, very concerning and frequent heart palpitations, bloating in my stomach area, fatigue, chest pressure and chest pain. I have been to 3 cardiologists and my most recent finally ordered a stress test and very thorough echocardiogram which found the heart disease. I did a EKG and echo test before w/ the other doctors, but they did not see it. The constant heart palpitations is what made me continue seeking doctors and figure out what is wrong. Apparently in my case, this all started from undiagnosed high blood pressure I've had for a very long time. I would say it's very likely you are just fine based on what you explain... just continue to keep an eye on your blood pressure and just stay in tune w/ your body/symptoms. If you still feel concerned, seek a second opinion from another cardiologist.
Hi there. Im not a doctor but offer some general advice. Do you have any other health issues? How is your Blood Pressure readings? Well you will know that 285 is a good bit too heavy. You need exercise regieme to get it down. Its unlikely your described symptoms are Heart related. You have passed Heart tests fine. If any Failure it would have shown in the stress test. If there was any LVH which would contribute to failure symptoms, that would probably be evident on ECG also. So you are in good shape it seems! Concentrate on weight loss & exercise and be guided by your cardiologist going forward
Your ticker has been checked out pretty thoroughly, and you're looking good in that department--for now.
However, as I'm sure you know, 285 lbs is bit much for your height, and even with a normal heart, you *will* puff and blow with mild exertion simply from moving the weight around.
At only 19 years, if your family heart history is good, you're probably OK, but the truth is that you are no longer a growing kid. To be on the safe side, even a young male should be lighter relative to his height, and should exercise regularly.
To answer your original question, though, here is what the early signs of heart failure feel like:
