Brief Summary:
Efficacy of the Pressure Optimization Protocol (POP) versus Conventional Stent Deployment Strategy during Primary PCI: An Open Label Randomized Clinical Trial The investigators will compare conventional rapid stent inflation/deflation during primary PCI with higher pressure and prolonged duration of stent deployment
Study Hypothesis: The POP in stent deployment is superior to the conventional stent deployment approach with a significantly higher achievement of the TIMI III flow, significantly lesser occurrence of slow flow/no-reflow, and significantly higher rate of ST-Segment resolution during primary PCI.
Study Hypothesis: The POP in stent deployment is superior to the conventional stent deployment approach with a significantly higher achievement of the TIMI III flow, significantly lesser occurrence of slow flow/no-reflow, and significantly higher rate of ST-Segment resolution during primary PCI.
Detailed Description:
Primary Objective The primary objective is to compare the rate of TIMI III flow achievement, slow flow/no-reflow, and ST-segment resolution between POP versus conventional stent deployment strategy during Primary PCI.
Secondary Objective The secondary objective is in-hospital outcome (to compare the rate of major adverse cardiovascular events (MACE) during hospitalization between POP versus conventional stent deployment strategy during Primary PCI.) Material and Methods Study design: An open-label randomized controlled trial (RCT) with blinded outcome assessment Setting: Cath Lab NICVD Karachi ,Hyderabad and Sukkur Duration of study: 6 months Stent Deployment Protocol: Patients will be randomly assigned to either POP or conventional stent deployment approach groups in 1:1 ratio using the block randomization method.
SAMPLE SIZE : 400 patients will be randomized into 2 groups with 1:1 Concealment: Allocation schema will remain accessible to the randomization and allocation team and will be communicated to the screening and recruitment team on a patient-on-patient basis.
Blinding: This will be an open-label study, however, the outcome assessment will be blinded. A de-identified CD and post-PCI ECG with a unique tracking ID will be evaluated by the team of independent consultants, who will be blinded to the stent placement approach, and primary outcome variables i.e. TIMI flow, slow-flow/no-reflow, and ST-segment resolution will be assessed.
Immediately post-procedure, a de-identified CD and post-PCI ECG with a unique tracking ID will be evaluated by the team of independent consultants, who will be blinded to the stent placement approach, and primary outcome variables i.e. TIMI flow, slow-flow/no-reflow, and ST-segment resolution will be assessed. All the patients will be followed at 30 days and incidence of MACE will be recorded.
In order to ensure the integrity and reliability of the data, all procedures and imaging assessments will be carried out by clinicians and technicians trained and standardized in the respective methodologies. Moreover, data will be stored in a secure, electronic database with restricted access to maintain patient confidentiality and data security. Regular data audits will be conducted to ensure accuracy and consistency throughout the trial.
Data Analysis:
Firstly, patient demographics and baseline clinical characteristics will be summarized using means and standard deviations for continuous variables and frequencies with percentages for categorical variables. Kaplan-Meier survival analysis will be used to determine the time-to-event data for outcomes such as target vessel failure, target vessel revascularization, cardiac death, and myocardial infarction. Log-rank tests will be employed to compare survival curves between the POP and Rapid I/D groups. Cox proportional hazards models will be used to compute hazard ratios (HRs) and their 95% confidence intervals (CIs) for each outcome of interest, adjusting for potential confounders.
For categorical outcomes, chi-squared tests or Fisher's exact tests will be used, as appropriate. Continuous outcomes will be assessed using t-tests or Mann-Whitney U tests based on data distribution. Any unmatched or imbalanced variables between the two groups will be controlled using propensity score matching. To address potential confounding factors and biases, a sensitivity analysis will be performed.
Lastly, all statistical analyses will be two-tailed, with a significance level set at p \< 0.05. Statistical software such as SPSS or R will be utilized for the analysis.
