Researchers found that at around 6:30 a.m. the circadian system sends out an increased amount of PAI-1 cells which blocks blood clots from breaking down. The more PAI-1 cells in the blood, the higher the risk for a blood clot that leads to a heart attack

I'm trying to make sense of my Echo Report, and it's causing me a bit of concern. It mentions things like a normal LV with normal systolic function and no segmental wall motion abnormalities, which I think sounds good. However, what got my attention was the mention of mild PAH and a mild TR. I'm a bit worried if the fast heart rate during the test, which was likely due to my anxiety, might have affected the results and led to a possible misdiagnosis of PAH. I mean, I haven't really had any symptoms other than a brief episode of PVC and sometimes a slightly fast heart rate. My resting rate stays between 50-65 BPM. I'm hoping for a little clarity on whether these findings are something to be concerned about. Can fast heart rate really make a difference in diagnosis, or am I misunderstanding things here?

My dad just had a 2D Echo after his ECG showed an irregular heartbeat, and I'm a bit worried. The report mentions grade 2 Diastolic Dysfunction and says something about an aortic valve being sclerotic. How serious is this? He's been feeling really weak and lethargic lately. What can we do to help him feel better?
