Life with LEF 30% & low blood pressure

I would think that your cardiologist could and should adjust your medicines. Dangerously low blood pressure, hypotension, is blood pressure lower than 90/60. It can cause dizziness, fainting and other problems. My husband had a massive heart attack, too, in late 2020 and has an EF of 20. It was much lower after his HA. He developed orthostatic hypotension(a form of low blood pressure that happens when standing up from sitting or laying down). He has fallen many times due to it resulting in blood clots to the brain, broken ribs, broken orbital bone etc. It’s under control again and luckily he has an excellent heart failure cardiologist at the Cleveland Clinic. But your doctor needs to listen to you when you tell him you are feeling dizzy and that you think your very low BP is causing it. Too low of BP can be as dangerous as too high.
