Background: Each year, up to 136,000 individuals suffering from acute coronary syndrome (ACS) are misdiagnosed and discharged from our nations’ emergency departments. We developed the Simple Acute Coronary Syndrome (SACS) score that tabulates a patient’s symptoms, ECG findings, risk factors, and cardiac markers (Figure 1). Our aim was to validate this novel scoring tool in its ability to identify the presence of obstructive coronary artery disease (CAD). Methods: A single-center retrospective chart review was performed after institutional review board approval. The charts of 42 consecutive patients who presented with ACS and who were treated with an invasive strategy were reviewed. Scores were calculated for each patient using the SACS tool as well as the Modified Thrombolysis in Myocardial Infarction (TIMI) ACS calculator. The study endpoint was the presence of at least one vessel obstructive CAD at cardiac catheterization. Descriptive statistics were employed. Results: The stratification of SACS and Modified TIMI scores for each of the 42 ACS patients is shown in Figure 2. In patients with a SACS score that was less than 3, none of these patients were found to have obstructive CAD at cardiac catheterization. For patients with a SACS score of 4 or higher, 100% of these patients were shown to have obstructive CAD. For patients with Modified TIMI scores of 1 and 2, 3/11 (27%) were found to have obstructive CAD. Conclusions: The novel SACS scoring system identifies ACS patients who will have obstructive CAD more reliably than more traditional scoring systems. The SACS scoring tool needs to be validated in larger scale studies.

Background A sizeable number of patients with a diagnosis of non-ST segment elevation acute coronary syndrome show non-obstructive coronary artery disease. In this study we assessed whether differences in vascular and cardiac autonomic function exist between non-ST segment elevation acute coronary syndrome patients with obstructive or non-obstructive coronary artery disease. Methods and results Systemic endothelium-dependent and independent vascular dilator function (assessed by flow-mediated dilation and nitrate-mediated dilation of the brachial artery, respectively) and cardiac autonomic function (assessed by time-domain and frequency-domain heart rate variability parameters) were assessed on admission in 120 patients with a diagnosis of non-ST segment elevation acute coronary syndrome. Patients were divided into two groups according to coronary angiography findings: (a) 59 (49.2%) with obstructive coronary artery disease (≥50% stenosis in any epicardial arteries); (b) 61 (50.8%) with non-obstructive coronary artery disease. No significant differences between the two groups were found in both flow-mediated dilation (5.03 ± 2.6 vs. 5.40 ± 2.5%, respectively; P = 0.37) and nitrate-mediated dilatation (6.79 ± 2.8 vs. 7.30 ± 3.4%, respectively; P = 0.37). No significant differences were also observed between the two groups both in time-domain and frequency-domain heart rate variability variables, although the triangular index tended to be lower in obstructive coronary artery disease patients (30.2 ± 9.5 vs. 33.9 ± 11.6, respectively; P = 0.058). Neither vascular nor heart rate variability variables predicted the recurrence of angina, requiring emergency room admission or re-hospitalisation, during 11.3 months of follow-up. Conclusions Among patients admitted with a diagnosis of non-ST segment elevation acute coronary syndrome we found no significant differences in systemic vascular dilator function and cardiac autonomic function between those with obstructive coronary artery disease and those with non-obstructive coronary artery disease.

The clinical significance of non-obstructive coronary artery disease is the subject of debate. Our objective was to evaluate the long-term cardiovascular prognosis associated with non-obstructive coronary artery disease in patients undergoing coronary angiography, and to conduct a stratification by sex, diabetes, and clinical indication. We designed a multi-centre retrospective longitudinal observational study of 3265 patients that were classified into three groups: normal coronary arteries (lesion <20%, 1426 patients), non-obstructive coronary artery disease (20–50%, 643 patients), and obstructive coronary artery disease (>70%, 1196 patients). During a mean follow-up of 43 months, we evaluated a combined cardiovascular event: acute myocardial infarction, stroke, hospitalization for heart failure, or cardiovascular death. Multivariable-adjusted Cox proportional hazard models showed a worse prognosis in patients with non-obstructive coronary artery disease, in comparison with patients of normal coronary arteries group, in the total population (hazard ratio 1.72, 95% confidence interval 1.23–2.39; p for trend <0.001), in non-diabetics (hazard ratio 2.12, 95% confidence interval: 1.40–3.22), in women (hazard ratio 1.75, 95% confidence interval 1.10–2.77), and after acute coronary syndrome (hazard ratio 2.07, 95% confidence interval 1.25–3.44). In conclusion, non-obstructive coronary artery disease is associated with an impaired long-term cardiovascular prognosis. This association held for non-diabetics, women, and after acute coronary syndrome.

Abstract Aims Distribution of wall motion abnormalities (WMA) in young patients presenting with acute coronary syndrome (ACS) is not well described. Methods and results We included 91 consecutive young patients (≤45 years at presentation) with ACS with obstructive or without obstructive coronary artery disease referred from October 2013 until March 2021 to our clinic. Wall motion abnormalities, wall motion score index (WMSI) and left ventricle ejection fraction (LVEF) were evaluated. A wall motion abnormality in at least one segment was present in 78.7% of patients. Mean LVEF was 50.9 ± 8.8% and mean WMSI was 1.38 ± 0.37%. Akinesia of at least one segment was present in 49.4%, dyskinesia and aneurysm were rare (1.1%, respectively). Ventricular thrombus was observed in 4.7%. Distribution of wall motion abnormalities is presented in Figure A. Most frequently WMA affected the apex and the basal inferior wall. The severity of WMA for each segment is presented in Figure B. The mean highest severity of WMA affected the apex, and the inferior and infero-septal wall. In the subgroup of patients presenting without obstructive coronary artery disease, WMA were less prevalent (37.5%), LVEF was higher (57.1% vs. 50.4% P = 0.032), and WMSI was lower (1.16% vs. 1.40% P = 0.07), but similarly affected with higher frequency the apex area. Conclusions In conclusion, WMA are frequent in young patients presenting with ACS, mostly affecting the apex. More severe abnormalities of wall kinesis affect the apex and the inferior and infero-septal wall.
