The primary investigator-initiated examine of distant pulmonary artery strain monitoring has discovered that it improves high quality of life and reduces coronary heart failure hospitalizations in sufferers with persistent coronary heart failure. The findings are offered in the present day in a late breaking science session at Coronary heart Failure 2023, a scientific congress of the European Society of Cardiology (ESC), and revealed in The Lancet.
Principal investigator Dr. Jasper Brugts of Erasmus College Medical Centre, Rotterdam, the Netherlands stated: “Pulmonary artery strain is a marker of hemodynamic congestion, which happens a number of weeks earlier than signs develop, offering a window of alternative to forestall overt congestion and subsequent hospitalization. In MONITOR-HF, physicians set a hemodynamic monitoring goal which enabled them to offer tailor-made therapies reminiscent of diuretics and different drugs.”
A number of questions remained after two earlier trials of pulmonary artery strain monitoring in sufferers with persistent coronary heart failure in North America. The CHAMPION trial, revealed in 2011, confirmed a constructive lead to sufferers with New York Coronary heart Affiliation (NYHA) class III coronary heart failure, a mean ejection fraction of 30%, a earlier coronary heart failure hospitalization, and comparatively low ranges of background guideline-directed medical remedy. GUIDE-HF, revealed in 2021, had a impartial outcome within the general evaluation which can have been associated to enrolling a broader and decrease danger inhabitants, or modification by COVID-19. A pre-specified subgroup evaluation restricted to follow-up previous the COVID-19 pandemic yielded a constructive outcome.
Coronary heart failure tips state that pulmonary artery strain monitoring has unsure worth however could also be thought of (stage IIb); uptake in Europe is due to this fact marginal. European knowledge have been wanted evaluating pulmonary artery strain monitoring to straightforward of care with excessive ranges of background medical remedy. MONITOR-HF examined the impact of hemodynamic monitoring on high quality of life and coronary heart failure hospitalizations towards up to date commonplace of care within the Netherlands.
The trial enrolled 348 sufferers from 25 facilities within the Netherlands. Sufferers had persistent coronary heart failure, any ejection fraction, NYHA class III signs and a earlier coronary heart failure hospitalization or pressing go to requiring intravenous diuretics up to now 12 months. The typical age was 69 years, 25% have been girls, and the imply ejection fraction was 30%. Contributors have been randomly allotted 1:1 to pulmonary artery strain monitoring on high of typical care or typical care alone (together with entry to common lab measurements reminiscent of natriuretic peptides and yearly echocardiography). All sufferers have been adopted up for at the very least 12 months. The typical period of comply with up was 18 months and the utmost was 48 months.
Sufferers within the monitoring group had a small, wi-fi, battery-free sensor implanted into the pulmonary artery by way of the femoral vein. A strain measurement was taken each morning in about 18 seconds and readings have been despatched to a safe web site. Physicians accessed the info and set a goal strain for every affected person which might point out the necessity to overview drug remedy.
The first endpoint was the change in high quality of life measured by the Kansas Metropolis Cardiomyopathy Questionnaire (KCCQ) at 12 months and the secondary endpoint was the variety of coronary heart failure hospitalizations and/or pressing visits requiring intravenous diuretics throughout follow-up.
At 12 months, the typical change within the KCCQ general abstract rating was +7 factors within the monitoring group and -0.2 factors within the typical care group, yielding a imply distinction between teams of seven.1 factors in favor of monitoring (p=0.013). Throughout a imply follow-up of 1.8 years there have been 117 coronary heart failure hospitalizations or pressing visits within the monitoring group and 212 within the typical care group, which represents a 44% discount with monitoring (hazard ratio 0.56; 95% confidence interval 0.38–0.84; p<0.01).
This remedy profit was constant in subgroups with an ejection fraction of ≤40% and >40%. The process was comparatively secure and dependable with a 97.7% freedom from machine or system associated issues and 98.8% freedom from sensor failure throughout follow-up.
Greater than 85% of individuals with coronary heart failure with decreased ejection fraction have been on beta-blockers, renin-angiotensin system inhibitors and mineralocorticoid receptor antagonists. The uptake of angiotensin receptor-neprilysin inhibitors (ARNI) and sodium-glucose co-transporter-2 inhibitors (SGLT2) was excessive and elevated through the course of follow-up, with 60% of controls on ARNI and 30% on SGLT2 inhibitors at 12 months. This stage of remedy implies that any extra good thing about pulmonary artery strain monitoring was actually on high of applicable ranges of guideline directed medical remedy.”

He concluded: “Pulmonary artery strain monitoring confirmed a considerable and vital impact on high quality of life and coronary heart failure hospitalizations which is very related for sufferers, physicians and hospitals. The precept of administration by exception ensures that physicians solely want to reply to sufferers exterior their threshold window, making this an environment friendly methodology with a low time requirement.”
