Late arrival ST-segment elevation myocardial infarction (STEMI) is defined as a patient-related delay > 12 hours. It is estimated to represent a significant portion of STEMI patients. As reflected by society guidelines, this group of patients impose great therapeutic challenge, namely due to controversy in the literature regarding optimal care, together with major adverse clinical outcomes [1]. In addition to a possible myocardial infarction (MI), mechanical complications include ventricular septal defect (VSD), left ventricular (LV) free wall, or papillary muscle rupture. Prompt diagnosis and intervention are crucial to improve outcomes as post-infarction ventricular septal defect (PIVSD) carries a high mortality rate. We describe the successful management of a large VSD complicated by cardiogenic shock in a latecomer STEMI patient with complex coronary artery disease (CAD).

Background: Acute coronary syndrome (ACS) represents a spectrum of ischemic myocardial disease including unstable angina (UA), non-ST-segment elevation myocardial infarction (NSTEMI), and ST-elevation myocardial infarction (STEMI). Various prognostic scores were developed for patients presenting with NSTEMI-ACS. Among these scores, the GRACE risk score offers the best discriminative performance for prediction of in-hospital and 6-month mortality. However, the GRACE score is limited and cannot be used in several ethnic populations. Moreover, it is not predictive of clinical outcomes other than mortality.

Objective: To assess the prognostic value of traditional cardiovascular risk factors and laboratory biomarkers in predicting 6-month major adverse cardiac and cerebrovascular events (MACCE), including hospitalization, recurrent percutaneous coronary intervention (PCI), stroke, and cardiovascular mortality in patients with NSTEMI treated with PCI.

Methods: This retrospective study included consecutive patients admitted with an initial diagnosis of NSTEMI to the cardiac intensive care unit (CICU) at the Tzafon Medical Center, Israel, between April 2015 and August 2018 and treated by PCI within 48 hours of admission.

Results: A total of 223 consecutive patients with NSTEMI treated by PCI were included in the study. Logarithmebrain natriuretic peptide (LogₑBNP), prior MI, and Hb levels were found to be significant predictors of any first MACCE. Only logₑBNP was found to be an independent predictor of a first MACCE event by multivariate logistic regression analysis.

Conclusions: LogₑBNP is an independent predictor of worse prognosis in patients with NSTEMI. Routine evaluation of BNP levels should be considered in patients admitted with NSTEMI.

Background: Tricuspid regurgitation (TR) is associated with adverse prognosis in various patient populations, but currently no data is available about the prevalence and prognostic implication of TR in ST-segment elevation myocardial infarction (STEMI) patients.

Objectives: To investigate the possible implication of TR among STEMI patients.

Methods: We conducted a retrospective study of STEMI patients undergoing primary percutaneous coronary intervention (PCI) and its relation to major clinical and echocardiographic parameters. Patient records were assessed for the prevalence and severity of TR, its relation to the clinical profile, key echocardiographic parameters, in-hospital outcomes, and long-term mortality. Patients with previous myocardial infarction or known previous TR were excluded.

Results: The study included 1071 STEMI patients admitted between September 2011 and May 2016 (age 61 ± 13 years; predominantly male). A total of 205 patients (19%) had mild TR while another 32 (3%) had moderate or greater TR. Patients with significant TR demonstrated worse echocardiographic parameters, were more likely to have in-hospital complications, and had higher long-term mortality (28% vs. 6%; P < 0.001). Following adjustment for significant clinical and echocardiographic parameters, mortality hazard ratio of at least moderate to severe TR remained significant (hazard ratio 2.44; 95% confidence interval 1.06–5.62; P = 0.036) for patients with moderate-severe TR.

Conclusions: Among STEMI patients after primary PCI, the presence of moderate-severe TR was independently associated with adverse outcomes and significantly lower survival rate

Conclusions: Among STEMI patients after primary PCI, the presence of moderate to severe TR was independently associated with adverse outcomes and significantly lower survival rate

Background: Data suggest that subclinical hypothyroidism (SCH) is associated with progression of chronic renal disease; however, no study to date has assessed the possible relation between SCH and acute deterioration of renal function.

Objectives: To investigate the possible relation between SCH and acute kidney injury (AKI) in a large cohort of patients with ST-elevation myocardial infarction (STEMI) treated with primary coronary intervention (PCI).

Methods: We evaluated thyroid stimulating hormone (TSH) and free T4 levels of 1591 STEMI patients with no known history of hypothyroidism or thyroid replacement treatment who were admitted to the coronary care unit (October 2007–August 2017). The presence of SCH was defined as TSH levels ≥ 5 mU/ml in the presence of normal free T4 levels. Patients were assessed for development of AKI ( 0.3 mg/dl increase in serum creatinine, according to the KDIGO criteria).

Results: The presence of SCH was demonstrated in 68/1593 (4.2%) STEMI patients. Patients presenting with SCH had more AKI complications during the course of STEMI (20.6% vs. 9.6 %; P = 0.003) and had significantly higher serum creatinine change throughout hospitalization (0.19 mg/dl vs. 0.08 mg/dl, P = 0.04). No significant difference was present in groups regarding baseline renal function and the amount of contrast volume delivered during coronary angiography. In multivariate logistic regression model, SCH was independently associated with AKI (odds ratio = 2.19, 95% confidence interval 1.05–4.54, P =0.04).

Conclusions: Among STEMI patients treated with PCI, the presence of SCH is common and may serve as a significant marker for AKI.

Background: Door-to-balloon time (DTBT) ≤ 90 minutes has become an important quality indicator in the management of ST-elevation myocardial infarction (STEMI). We identified three specific problems in the course from arrival of STEMI patients at our emergency department to initiation of balloon inflation and determined an intervention comprised of specific administrative and professional steps. The focus of the intervention was on triage within the emergency department (ED) and on increasing the efficiency and accuracy of electrocardiography interpretation.

Objectives: To examine whether our intervention reduced the proportion of patients with DTBT > 90 minutes.

Methods: We compared DTBT of patients admitted to the ED with STEMI during the year preceding and the year following implementation of the intervention.

Results: Demographic and clinical characteristics at presentation to the ED were similar for patients admitted to the ED in the year preceding and the year following intervention. The year preceding intervention, DTBT was > 90 minutes for 19/78 patients (24%). The year after intervention, DTBT was > 90 minutes for 17/102 patients (17%). For both years, the median DTBT was 1 hour. Patients with DTBT > 90 minutes tended to be older and more often female. Diagnoses in the ED were similar between those with DTBT ≤ 90 minutes and > 90 minutes. In-hospital mortality was 17% (13/78) and 14% (14/102) for the respective time periods.

Conclusions: An intervention specifically designed to address problems identified at one medical center was shown to decrease the proportion of patients with DTBT > 90 minutes.
