The Effect of War on STEMI Incidence: Insights from Intensive Cardiovascular Care Unit Admissions.

(1) Background : The impact of armed conflicts on public health is undeniable, with psychological stress emerging as a significant risk factor for cardiovascular disease (CVD). Nevertheless, contemporary data regarding the influence of war on CVD, and especially on acute coronary syndrome (ACS), are scarce. Hence, the aim of the current study was to assess the repercussions of war on the admission and prognosis of patients admitted to a tertiary care center intensive cardiovascular care unit (ICCU). (2) Methods : All patients admitted to the ICCU during the first three months of the Israel-Hamas war (2023) were included and compared with all patients admitted during the same period in 2022. The primary outcome was in-hospital mortality. (3) Results : A total of 556 patients (184 females [33.1%]) with a median age of 70 (IQR 59-80) were included. Of them, 295 (53%) were admitted to the ICCU during the first three months of the war. Fewer Arab patients and more patients with ST-segment elevation myocardial infraction (STEMI) were admitted during the war period (21.8% vs. 13.2%, p < 0.001, and 31.9% vs. 24.1%, p = 0.04, respectively), whereas non-STEMI (NSTEMI) patients were admitted more frequently in the pre-war year (19.3% vs. 25.7%, p = 0.09). In-hospital mortality was similar in both groups (4.4% vs. 3.4%, p = 0.71; HR 1.42; 95% CI 0.6-3.32, p = 0.4). (4) Conclusions : During the first three months of the war, fewer Arab patients and more STEMI patients were admitted to the ICCU. Nevertheless, in-hospital mortality was similar in both groups.
