Insights
Unplanned readmissions after percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) occurred in 11.5% of patients within one year. Female gender, chronic kidney disease, multiple stents, and heart failure predicted readmission.
Area of Science:
- Cardiology
- Interventional Cardiology
- Public Health
Background:
- Unplanned readmissions post-PCI for STEMI impact healthcare systems.
- Limited data exists on long-term readmission rates and causes.
- No prior studies have examined PCI readmissions in STEMI patients in the Arab Gulf region.
Purpose of the Study:
- To determine the rates, causes, and predictors of one-year unplanned readmissions post-PCI in STEMI patients.
- To provide region-specific data from Qatar, an Arab Gulf country.
Main Methods:
- Retrospective cohort study of 1,257 STEMI patients undergoing PCI.
- Data collected from January 2016 to September 2018 at Hamad Medical Corporation, Qatar.
- Patients categorized based on experiencing one or more unplanned readmissions within one year.
Main Results:
- The all-cause readmission rate was 11.5% within one year, with 8.2% due to cardiac causes.
- Predictors for all-cause readmission included female gender (aOR=4.14), chronic kidney disease (aOR=2.76), multiple stents (aOR=1.66), and heart failure (aOR=2.36).
Conclusions:
- The study identified key predictors of one-year readmission in STEMI patients post-PCI.
- Findings underscore the need for targeted management strategies for high-risk individuals to reduce readmission rates.
Background:
Unplanned readmissions after percutaneous coronary intervention (PCI) in patients with ST-elevation myocardial infarction (STEMI) significantly impact healthcare systems. However, most of the existing literature focuses on short-term readmission rates and causes, with limited data on long-term readmissions. To date, no studies have evaluated the unplanned readmission post-PCI in STEMI patients within the Arab Gulf region. This study aimed to determine the rates, causes, and predictors of readmission post-PCI among STEMI patients over a one-year follow-up in Qatar, one of the Arab Gulf countries.
Methods:
We conducted a single-center retrospective cohort study at Hamad Medical Corporation in Qatar, involving 1,257 patients who underwent PCI during their index STEMI admission between January 1, 2016, and September 30, 2018. Patients were divided into two groups; (1) those who had one or more unplanned readmission within one year after PCI; (2) and those who did not have readmissions. The outcomes evaluated were the rates, causes, and predictors of all-cause and cardiac readmissions within one year post-PCI.
Results:
The mean age of the study population was 51 ± 10 years, and male gender presented 96%. The rate of all-cause readmission within one year post-PCI was 11.5%, with 8.2% due to cardiac reasons. Positive predictors of all-cause readmission included female gender (aOR = 4.14, 95% CI 2.10-8.18, p < 0.001), chronic kidney disease (aOR = 2.76, 95% CI 1.07-7.08, p = 0.035), more than one stent during PCI (aOR = 1.66, 95% CI 1.09-2.55, p = 0.019), and clinical heart failure during the index admission (aOR = 2.36, 95% CI 1.49-3.74, p < 0.001).
Conclusion:
This study highlights the need for targeted management strategies for high-risk populations to reduce readmission rates.
