Dapagliflozin on Hypotensive Heart Failure Patients After Sacubitril/Valsartan Therapy
Study Details
Study Description
Brief Summary
The DAPA-HF trial demonstrated that dapagliflozin was able to reduce the risk of worsening heart failure events and cardiovascular death comparing to placebo in patients with reduced ejection fraction further to standard of care. However, hypotensive patients who generally have higher risks comparing to normotensive patients, were under represented in the DAPA-HF. The investigators aimed to evaluate clinical effects of dapagliflozin on hypotensive heart failure patients receiving chronic sacubitril/valsartan treatment.

Detailed Description
The DAPA-HF trial demonstrated that dapagliflozin was able to reduce the risk of worsening heart failure (HF) events and cardiovascular death comparing to placebo in patients with reduced ejection fraction further to standard of care. However, hypotensive patients who generally have higher risks comparing to normotensive patients, were under represented in the DAPA-HF. The investigators aimed to evaluate clinical effects of dapagliflozin on hypotensive HFrEF patients receiving chronic sacubitril/valsartan (Sal/Val) treatment.
This is an investigator-initiated, interventional, prospective. open-label study. The inclusion criteria were (1) chronic symptomatic HF with New York Heart Association (NYHA) class II-IV and LVEF less than 40%, (2) treatment with stable and maximal tolerable dose of Sac/Val, beta-blocker with or without mineralocorticoid receptor antagonist (MRA), (3) 6-minute walking-distance (6MWD)≥ 100meters and ≤425 meters at enrollment, (4) systolic blood pressure ≤100 mmHg at enrollment. The exclusion criteria were (1) type 1 diabetes mellitus, (2) patients previously treated with any sodium glucose co-transporter 2 inhibitor (SGLT2i).
After applying the inclusion and exclusion criteria, if the participants had type 2 diabetes mellitus, the participants will receive dapagliflozin 10mg daily directly. If the participants did not have history of diabetes mellitus, the participants will be allocated to either receiving dapagliflozin 10mg daily or receiving standard heart failure treatment without dapagliflozin.
Vital signs and laboratory tests were examined at baseline, 2-week, 4-week and 12-week. Six-minute-walking-test, five-level EuroQol five dimensions (EQ-5D-5L) questionnaire and visual analogue scale (VAS) were collected at baseline and at 12-week.

Outcome Measures
Primary Outcome Measures
- 6-minute walking distance [12 weeks]
Measuring walking distance within 6 minutes
Secondary Outcome Measures
- EQ-5D-5L [12 weeks]
Measuring health status. Health status is measured in terms of five dimensions (5D); mobility, self-care, usual activities, pain/discomfort, and anxiety/depression.This version of EQ-5D has five-level scale, The number of levels of severity was classified into: having no problems, having slight problems, having moderate problems, having severe problems and being unable to do/having extreme problems. This version can define 3,125 (5x5x5x5x5) different health states. Valuation of the EQ-5D-5L was then calcuated by the Taiwanese hybrid model, range from -1.0259 to 1. [PLoS One 13(12):e0209344]. Higher score indicates better health status.
- EQ-Visual analogue scale (EQ-VAS) [12 weeks]
Evaluating the participants' overall health status. The participant would be asked to mark health status on the day of the interview on a 20 cm vertical scale with end points of 0 and 100. There are notes at the both ends of the scale that the bottom rate (0) corresponds to " the worst health you can imagine", and the highest rate (100) corresponds to "the best health you can imagine".
