Exclusion criteria
Exclusion criteria: Type-1 diabetics or patients having any history of DKA Patients having eGFR = 25 ml/ min/ 1.73 m2 as per (CKD-EPI formula), systolic blood pressure (SBP) < 95 mmHg Patients having MI, unstable angina, stroke, acute heart failure (HF) or any hospitalization due to acute HF <4 weeks preceding enrolment Patients undergoing PCI /CABG or valvular replacement, any previous transplantation of heart or infixing of ventricular assistance device (VAD), implantation of Cardiac resynchronization therapy (CRT) within 3 months preceding enrolment or any plan to undergo after randomization Patients having active myocarditis, uncorrected primary valvular disease, restrictive or hypertrophic (obstructive) cardiomyopathy; bradycardia, 2nd or 3rd degree heart block without having any pacemaker Patients received any SGLT2i within 12 weeks preceding screening visit or hypersensitivity to Dapagliflozin Pregnant ladies and nursing mothers, severe COPD leading to dyspnea, any malignancy or hepatic impairment
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary outcome will include exploration of clinical efficacy of Dapagliflozin in CHF patients. Timepoint: At day 0 and after 12 weeks. Method of measurement: By biochemical parameters including (BNP/ NT-pro BNP, serum uric acid, creatinine, HbA1c, urine R/E, spot urine P/C ratio, echocardiography), improvement in quality of life by KCCQ questionnaire, NYHA functional class. SAFETY ANALYSIS OF DAPAGLIFLOZIN will be analyzed by observing number of events of major hypoglycemia, hypotension urogenital infection, fournier’s gangrene, DKA and any amputation before and after intervention. MAJOR ADVERSE CARDIOVASCULAR EVENTS (MACE) including heart failure hopsitalisations, urgent heart failure visits, stroke, arrhythmia, MI, acute kidney injury and cardiogenic death will be observed for a number of episodes before and after intervention with Dapagliflozin. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1)To determine the prevalence of Dapagliflozin transporter genes SLC5A2 for its single nucleotide polymorphism (SNPs) of SLC5A2 (rs3813008 G>A ,rs9934336 G > A and rs3116150 G>A) encoding SGLT2 transporter in Pakistani CHF population. 2)To estimate steady state plasma drug levels of Dapagliflozin and evaluate association of (SNPs) of Dapagliflozin transporter genes on steady state concentration in Pakistani CHF patients.3)To evaluate association of SNPs and plasma levels of Dapagliflozin with clinical efficacy in Pakistani CHF patients. Timepoint: After intervention of 12 weeks with Dapagliflozin. Method of measurement: Polymerase Chain Reaction (PCR) will be performed for genetic analysis of SNPs of SLC5A2 (rs3813008 G>A and rs3116150 G>A) followed by Restriction Fragment Length Polymorphism (RFLP). Allele Specific- Polymerase Chain Reaction (AS-PCR) will be performed for genotyping of variant allele (rs9934336 G>A) of SLC5A2. Drug levels will be estimated by HPLC. | — |
