SGLT2i and KNO3 in HFpEF - The SAK HFpEF Trial
Forrás: ClinicalTrials.gov · Utoljára frissítve: 2026. ápr. 16.
Rövid összefoglaló (regiszter, angolul)
This study will test whether pharmacologic agents that may improve mitochondrial function and energy fuel metabolism [Empagliflozin (Empa)], with and without additional supplements that increase perfusion and fatty acid oxidation [Potassium Nitrate (KNO3)], improve submaximal exercise endurance and skeletal muscle oxidative phosphorylation capacity (SkM OxPhos) in participants with Heart Failure with Preserved Ejection Fraction (HFpEF).

Korábbi kezelés
- Treatment with organic nitrates or phosphodiesterase inhibitors that cannot be interrupted
- Clinically significant lung disease as defined by: Chronic Obstructive Pulmonary Disease Stage III or greater GOLD criteria (FEV1<50%), treatment with oral steroids within the past 6 months for an exacerbation of obstructive lung disease, current use of supplemental oxygen aside from nocturnal oxygen for the treatment of obstructive sleep apnea.
- Desaturation to <90% on the baseline maximal effort cardiopulmonary exercise test will also be grounds for exclusion
- Current use of, or prior intolerance to, an SGLT2i
- Active participation in another study that utilizes an investigational agent (observational studies/registries allowed)
Más betegség
- Uncontrolled atrial fibrillation, as defined by a resting atrial fibrillation heart rate > 100 beats per minute at the time of the baseline assessment
- Moderate or greater left sided valvular disease (mitral regurgitation, aortic stenosis, aortic regurgitation), mild or greater mitral stenosis, severe right-sided valvular disease
- Clinically significant pericardial disease, as per investigator judgment
- Current angina due to clinically significant epicardial coronary disease, as per investigator judgment
- Acute coronary syndrome or coronary intervention within the past 2 months
- Primary pulmonary artery hypertension (WHO Group 1 Pulmonary Arterial Hypertension)
- Clinically-significant ischemia, as per investigator's judgement, on stress testing without either (1) subsequent revascularization, (2) an angiogram demonstrating the absence of clinically significant epicardial coronary artery disease, as per investigator judgment; (3) a follow-up 'negative' stress test, particularly when using a more specific technique (i.e., a negative perfusion imaging test following a 'positive' ECG stress test)
- Exercise-induced regional wall motion abnormalities on the echocardiographic assessment during the baseline maximal effort cardiopulmonary exercise test will also be exclusionary
- Type I Diabetes
- History of ketoacidosis
- Allergy to beets
- Any condition that, in the opinion of the investigator, may interfere with the completion/performance of the study. This may include comorbid or psychiatric conditions that may impede successful completion of the protocol, or logistical concerns (e.g., inability to travel to the exercise unit).
Laborértékek
- Hemoglobin < 10 g/dL
- Left ventricular ejection fraction < 45% on a prior echocardiogram or cardiac MRI, unless the reduced LVEF occurred within the context of an uncontrolled supraventricular arrhythmia, with return of a normal ejection fraction following treatment of the arrhythmia
- Significant liver disease impacting synthetic function or volume control (ALT/AST > 3x ULN, Albumin < 3.0 g/dL)
- eGFR < 30 mL/min/1.73m2.
- Serum potassium > 5.0 mEq/L on baseline testing
Életkor
- Age <18 years old
Egyéb
- Pregnancy: Women of childbearing potential will undergo a urine pregnancy test during the screening visit.
- Subject inability/unwillingness to exercise
- Known hypertrophic, infiltrative, or inflammatory cardiomyopathy
- Methemoglobin > 5%
- Ongoing maintenance of a 'Ketogenic Diet' (low carbohydrate, high fat)
- Severe right ventricular dysfunction
- Baseline resting seated systolic blood pressure > 180 mmHg or < 100 mmHg
- Persistently low or high seated blood pressure or orthostatic blood pressure response to the transition from supine to standing (>20 mmHg reduction in systolic blood pressure 2-3 minutes after standing, or a fall in SBP to < 90 mmHg) at the baseline visit
A regiszterben nem jelölt feltételek
- Inclusion:
- NYHA Class II-III symptoms 2. Left ventricular ejection fraction >= 50% 3. Stable medical condition for at least 2 weeks, as per investigator judgment 4. Prior or current evidence for elevated filling pressures, as evidenced by at least one of the following:
- Mitral early (E)/septal tissue annular (e') velocity ratio > 8, in the context of a septal e' velocity <=7 cm/s or a lateral e' <= 10 cm/s, in addition to one of the following: i. Large left atrium (LA volume index > 34 mL/m2) ii. Chronic loop diuretic use for control of symptoms iii. Elevated natriuretic peptides within the past year (e.g., NTproBNP > 125 pg/mL in sinus rhythm or > 375 pg/mL if in atrial fibrillation) b. Mitral E/e' ratio > 14 at rest or during exercise c. Elevated invasively-determined filling pressures previously (resting left ventricular end-diastolic pressure >= 16 mm Hg or pulmonary capillary wedge pressure >= 15 mmHg; or PCWP/LVEDP >= 25 mmHg with exercise) d. Prior episode of acute heart failure requiring IV diuretics
