Personalized Pacing: A New Paradigm for Patients With Diastolic Dysfunction or Heart Failure With Preserved Ejection Fraction (myPACE)
Pacemaker, Diastolic Dysfunction, Diastolic Heart Failure
About this trial
This is an interventional treatment trial for Pacemaker focused on measuring Heart failure with preserved ejection fraction, Diastolic dysfunction, Resting heart rate, Personalized, Lower rate setting
Eligibility Criteria
Inclusion Criteria:
- Implanted pacemaker with either 1) intrinsic ventricular conduction or 2) conduction system or biventricular pacing or 3) RV pacing <2% and paced QRS duration <150ms
Clinical evidence of heart failure with preserved ejection fraction or diastolic dysfunction, based on:
- dyspnea with exertion
- or NYHA Class ≥ II heart failure
- or pulmonary edema on prior chest imaging or documented on exam
- or is taking loop diuretics for heart failure
- or had NTproBNP >400 ng/ml in the last 24 months
- or a heart failure hospitalization in the last 2 years
- or has diastolic dysfunction on echo
- or has left ventricular hypertrophy on echo
- or has left atrial (LA) dilation (LA volume/BSA index >28ml/m2)
Exclusion Criteria:

- Hemoglobin < 8 g/dL
- Participation in another clinical trial or registry study
- Inability to follow up for regularly scheduled pacemaker appointments or to follow up for this study
- Pregnant patients or patients of childbearing age without reliable contraceptive agent (intra-uterine device, birth control implant, compliance with contraception injections or contraception pills) for the duration of study participation

Arms of the Study
Arm 1
Arm 2
Experimental
Active Comparator
Lower rate set to a higher, personalized backup heart rate (myPACE)
Lower rate left at 60 beats-per-minute
Patients randomized to this group will have their pacemaker lower heart rate setting programmed to a personalized lower rate based on a resting heart rate algorithm.
Patients randomized to this group will have their pacemaker lower heart rate setting left at or programmed to the conventional pacemaker lower rate setting of 60bpm.
