First medical contact-to-balloon time and in-hospital outcomes of primary percutaneous coronary intervention for ST-elevation myocardial infarction in Jenin, Palestine: a retrospective cohort study (2023-2024).
Article in BMC cardiovascular disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPrimary percutaneous coronary intervention (PPCI) is the preferred reperfusion strategy for ST-elevation myocardial infarction (STEMI) when it can be delivered quickly. In Jenin governorate, most patients are first assessed at a single non-PCI governmental hospital before transfer to a PCI-capable center, and transfers may be slowed by movement restrictions, including Israeli checkpoints and road closures. We assessed adherence to the guideline first medical contact-to-balloon (FMC2B) target (≤ 120 min) and its association with in-hospital outcomes.
methodsWe retrospectively included consecutive adults with confirmed STEMI who underwent PPCI after inter-hospital transfer from Jenin Government Hospital to Ibn Sina Hospital between 1 January 2023 and 31 December 2024. First medical contact (FMC) was defined as the first documented physician assessment time at the referring emergency department. Patients who self-presented directly to the PCI center or were treated outside the transfer-to-PPCI pathway were excluded. The primary outcome was FMC2B ≤ 120 min. Secondary outcomes were in-hospital major adverse cardiac events (MACE: death, reinfarction, or heart failure). Multivariable logistic regression was used to evaluate predictors of delayed reperfusion and MACE.
resultsThe final cohort included 202 patients (mean age 56.8 ± 11.2 years; 89.6% men). Median FMC2B was 124 min (IQR 91-166) and 47.5% (95% CI 40.7-54.4) achieved FMC2B ≤ 120 min. The largest component of delay was the FMC-to-PCI-center arrival interval (median 67 min, IQR 47-111). In-hospital MACE occurred in 15.8% (n = 32) and was higher when FMC2B was > 120 min than when it was ≤ 120 min (22.6% vs. 8.3%, p = 0.007). After adjustment, FMC2B > 120 min remained independently associated with MACE (OR 3.54, 95% CI 1.39-8.99).
conclusionsIn this transfer-dependent STEMI system, fewer than half of patients met the FMC2B ≤ 120-minute target, and delayed reperfusion was associated with worse in-hospital outcomes. Quality improvement should focus on faster diagnosis and transfer coordination, along with early cath-lab activation, to reduce system delays.
