Will taking Cimlanod cause low blood pressure in patients with heart failure with reduced ejection fraction?
Cimlanod (BMS-986231) is a nitroxyl donor being studied for heart failure with reduced ejection fraction (HFrEF). It works by relaxing blood vessels and improving heart function, but this vasodilation can also cause blood pressure to drop. A meta-analysis of four studies involving 459 patients found that Cimlanod significantly increased the risk of hypotension compared to placebo 5. This means low blood pressure is a known side effect that doctors and patients should watch for.
What the research says
A meta-analysis pooled data from four studies with 459 HFrEF patients (278 on Cimlanod, 181 on placebo). The results showed that Cimlanod did not reduce all-cause mortality or cardiac death, but it did significantly increase the risk of hypotension (low blood pressure) 5. The risk ratio for hypotension was 1.51, meaning patients on Cimlanod were about 1.5 times more likely to experience low blood pressure than those on placebo 5. This effect is consistent with how Cimlanod works: it relaxes blood vessels (vasodilation), which can lower blood pressure. The meta-analysis also found that Cimlanod did not significantly increase overall adverse events or serious adverse events, but the hypotension risk was notable 5. Other sources in this set do not directly address Cimlanod, but they provide context on HFrEF treatments. For example, vericiguat, another vasodilator, showed no significant effect on flow-mediated dilation in a small pilot trial 4, and omecamtiv mecarbil, a different type of drug, showed a trend toward reduced arrhythmia risk 3. These differences highlight that each HFrEF medication has unique side effect profiles.
What to ask your doctor
- Given my current blood pressure and heart failure status, is Cimlanod a safe option for me?
- How would we monitor for low blood pressure if I start taking Cimlanod?
- What symptoms of low blood pressure should I watch for, and when should I call you?
- Are there other HFrEF medications that might have a lower risk of hypotension?
- If I experience dizziness or lightheadedness, should I stop the medication or adjust the dose?
