Hello,
The treatment started by your cardiologist by introducing 40 mg lisinopril is absolutely correct and in the best of your cardiac condition.The effective dose range for treating heart failure is 5-40 mg daily.
Lisinopril decreases the after load on the heart and decreases BP by reducing vasoconstriction which in turn benefits the heart.Since your EF is 25-30 %,so a high dose of lisinopril is desired.Studies have shown that patients with moderate to severe CHF(EF<20%) had 12% lower risk of death or hospitalization for any reason, if placed on a high dose of ACE inhibitor like Lisinopril compared to a low dose.
I would suggest that you comply with your doctor’s prescription as high doses of lisinopril significantly reduces mortality in CHF patients.
I hope that helps.Take care and pls do keep me posted.
Lisinopril takes pressure off the heart and even eyes if a person has glaucoma. Pressure buildup in the heart can lead to further heart failure. Usually, doctors want the blood pressure to be low to take the workload off of the heart. The percent of which your heart is working, does not mean that there is less pressure in your heart. Lisinopril is an ace inhibitor and has proven studies showing that it can extend ones lifespan unlike beta blockers. Blood pressure should be below the normal range of 120/72 and the heart rate probably in the 60's or a little higher. If your blood pressure is above normal, it is too high. Same with your heart rate. Lisinopril is a great medication to be on when there are heart issues. Doctors start patients off at a lower dose and work up gradually to the dose that the patient should be on, so that their body adjusts to the medication slowly.
