Please assess the completion status of the following clinical trial:

Trial Title: Novel Cardiac Rehabilitation in Patients Heart Failure and Preserved Ejection Fraction

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~1. NYHA class II or III symptoms~2. Referred by physician to CR with echocardiographic evidence of HFpEF defined as an ejection fraction ≥ 50 % and moderate to severe (grade II-III) diastolic dysfunction.~3. ≥ 50 years of age~4. Free of orthopedic or other medical problems that would limit participation in CR~5. Peak VO2 on baseline cardiopulmonary exercise test (CPX) \< 24 mL/kg/min in men and \<21 mL/kg/min in women~Exclusion Criteria:~1. Systolic dysfunction, per ejection fraction \< 50%; those with mild (grade I) diastolic dysfunction~2. Initial clinical responses observed during first 3 visits in CR or baseline exercise test that would preclude participation in study over-all (e.g., new onset/troublesome arrhythmia that warrants further investigation) or undergoing HIIT (e.g., claudication, balance issue)~3. Patients with exercise induced angina during CR or CPX testing or ST segment depression representative of myocardial ischemia during CPX testing~4. Pregnant or planning to become pregnant~5. Any patient recently hospitalized for heart failure will have to wait at least 2 weeks before starting CR, or until clinically stable per physician(whichever time period is greater)~6. Atrial fibrillation
