Patent Claims:	1. A method for treating and/or preventing HFpEF and/or at least one disease, disorder, or condition associated therewith, the method comprising administering to a non-diabetic human patient having structural heart disease and in need thereof a pharmaceutical composition comprising a therapeutically effective amount of at least one compound chosen from compounds of Formula (I) and prodrugs thereof, wherein the non-diabetic human patient having structural heart disease has a body mass index of <50 kg/m2 and a hemoglobin A1c of <5.7%, and wherein the at least one disease, disorder, and/or condition associated with HFpEF is chosen from skeletal muscle dysfunction, vascular dysfunction, hypertension, pulmonary hypertension, renal failure, anemia, atrial fibrillation, and major adverse cardiovascular events. 2. The method of claim 1, wherein the method is a method for treating HFpEF. 3. The method of claim 1, wherein the pharmaceutical composition further comprises at least one other therapeutic agent. 4. The method of claim 1, wherein the major adverse cardiovascular event is chosen from myocardial infarction, stroke, cardiovascular death, and cardiovascular hospitalization. 5. The method of claim 4, wherein the cardiovascular hospitalization is related to unstable or stable angina pectoris, heart failure, and/or coronary revascularization. 6. The method of claim 1, wherein the patient satisfies at least one of the following conditions: (a) the patient is ≥40 years old; (b) the patient has documented diagnosis of symptomatic heart failure NYHA class II-IV prior to treatment; (c) the patient has a medical history of symptoms and/or signs of heart failure ≥6 weeks with at least intermittent need for diuretic treatment prior to treatment; or (d) the patient has NT-proBNP of ≥300 μg/ml without ongoing atrial fibrillation/flutter or has NT-proBNP of ≥600 μg/ml with ongoing atrial fibrillation/flutter prior to treatment. 7. The method of claim 6, wherein at least one symptom and/or sign of heart failure is chosen from breathlessness, orthopnea, paroxysmal nocturnal dyspnoea, reduced exercise tolerance, fatigue, tiredness, increased time to recover after exercise, ankle swelling, elevated jugular venous pressure, hepatojugular reflex, third heart sound, laterally displaced apical impulse, >2 kg weight gain per week, weight loss in advanced HF, cachexia, reduced appetite cardiac murmur, peripheral oedema, pulmonary crepitations, reduced air entry and dullness to percussion at lung bases, tachycardia, irregular pulse, tachypnea, cheyne stokes respiration, hepatomegaly, ascites, cold extremities, oliguria, and/or narrow pulse pressure. 8. The method of claim 1, wherein the evidence of structural heart disease comprises left ventricular hypertrophy and/or left atrial enlargement. 9. The method of claim 8, wherein left ventricular hypertrophy is defined by septal thickness or posterior wall thickness ≥1.1 cm. 10. The method of claim 8, wherein left atrial enlargement is defined by left atrial width (diameter) ≥3.8 cm, left atrial length >5.0 cm, left atrial area ≥20 cm2, left atrial volume ≥55 mL, and/or left atrial volume index ≥29 mL/m2. 11. The method of claim 1, wherein the patient satisfies at least one of the following conditions: (a) the patient has not received intravenous heart failure therapy, including diuretics, for at least 12 hours prior to treatment; (b) the patient has not received therapy with an SGLT2 inhibitor within 4 weeks prior to treatment; (c) the patient does not have eGFR<25 mL/min/1.73 m2; (d) the patient does not have systolic blood pressure (BP)<95 mmHg on 2 consecutive measurements at 5-minute intervals prior to treatment; (e) the patient does not have systolic BP≥160 mmHg if not on treatment with ≥3 blood pressure lowering medications or >180 mmHg irrespective of treatments, on 2 consecutive measurements at 5-minute intervals prior to treatment; (f) the patient has not had a myocardial infarction, unstable angina, coronary revascularization, ablation of atrial flutter/fibrillation, or valve repair/replacement within 12 weeks prior to treatment; (g) the patient does not have planned coronary revascularization, ablation of atrial flutter/fibrillation or valve repair/replacement; (h) the patient has not had a stroke or transient ischemic attack within 12 weeks prior to treatment; (i) the patient does not have probable alternative or concomitant diagnoses which in the opinion of the treating physician could account for the patient's HF symptoms and signs; (j) the patient does not have primary pulmonary hypertension, chronic pulmonary embolism, severe pulmonary disease; (k) the patient does not have HF due to known infiltrative cardiomyopathy, active myocarditis, constrictive pericarditis, cardiac tamponade, known genetic hypertrophic cardiomyopathy or obstructive hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy/dysplasia, or uncorrected primary valvular disease; (l) the patient does not have a life expectancy of less than 2 years due to any non-cardiovascular condition, based on the treating physician's clinical judgement; (m) the patient does not have active malignancy requiring treatment (with the exception of basal cell or squamous cell carcinomas of the skin); or (n) the patient does not have acute or chronic liver disease with severe impairment of liver function. 12. The method of claim 11, wherein the patient satisfies each of conditions (a) through (n) of claim 11. 13. The method of claim 1, wherein the patient has left ventricular ejection fraction of ≥45%. 14. The method of claim 1, wherein the patient has left ventricular ejection fraction of ≥50%. 15. The method of claim 1, wherein the patient has left ventricular ejection fraction within the range of from about 40 to about 49%. 16. The method of claim 1, wherein the method reduces the occurrence of CV death compared to placebo. 17. The method of claim 1, wherein the method reduces the occurrence of hospitalization for HF compared to placebo. 18. The method of claim 1, wherein the method reduces the occurrence of an urgent HF visit compared to placebo. 19. The method of claim 1, wherein the method reduces the total number of hospitalizations for HF and CV death compared to placebo. 20. The method of claim 19, wherein the total number of hospitalizations is for first and/or recurrent hospitalizations. 21. The method of claim 1, wherein the method improves one or more of the patient reported outcomes measured by KCCQ. 22. The method of claim 1, wherein the method improves the NYHA class of the patient from baseline. 23. The method of claim 1, wherein the method reduces the occurrence of death from any cause compared to placebo. 24. The method of claim 1, wherein the method reduces the occurrence of hospitalization from any cause compared to placebo. 25. The method of claim 1, wherein the method improves the health status of the patient assessed by EQ-5D-5L questionnaire. 26. The method of claim 1, wherein the method improves the health status of the patient assessed by PGIS questionnaire. 27. The method of claim 1, wherein the method improves systolic BP of the patient from baseline. 28. The method of claim 1, wherein the method improves body weight of the patient from baseline. 29. The method of claim 1, wherein the method does not reduce eGFR of the patient from baseline. 30. The method of claim 1, wherein the method improves the KCCQ summary score, overall summary score, TSS, and/or QoL score of the patient. 31. The method of claim 1, wherein method comprises administering the pharmaceutical composition in addition to standard of care therapy. 32. The method of claim 31, wherein the standard of care therapy comprises treatments to control co-morbidities and/or treatments for reducing the composite of CV death and heart failure events. 33. The method of claim 32, wherein the heart failure events are chosen from hospitalization for HF and/or urgent HF visits.
