The aim of this retrospective study was to provide real-world data on lipid-lowering therapy (LLT) implementation and low-density lipoprotein cholesterol (LDL-C) target achievement in an ST-segment elevation myocardial infarction (STEMI) population, with a focus on very-high-risk patients according to European guidelines criteria. Methods: Included were all STEMI patients with available LDL-C and total cholesterol treated at a large tertiary center in Salzburg, Austria, 2018–2020 (n = 910), with stratification into very-high-risk cohorts. Analysis was descriptive, with variables reported as number, percentages, median, and interquartile range. Results: Among patients with prior LLT use, statin monotherapy predominated, 5.3% were using high-intensity statins, 1.2% were using combined ezetimibe therapy, and none were taking PCSK9 inhibitors at the time of STEMI. In very-high-risk secondary prevention cohorts, LLT optimization was alarmingly low: 8–22% of patients were taking high-intensity statins, just 0–6% combined with ezetimibe. Depending on the very-high-risk cohort, 27–45% of secondary prevention patients and 58–73% of primary prevention patients were not taking any LLTs, although 19–60% were actively taking/prescribed medications for hypertension and/or diabetes mellitus. Corresponding LDL-C target achievement in all very-high-risk cohorts was poor: <22% of patients had LDL-C values < 55 mg/dL at the time of STEMI. Conclusion: Severe shortcomings in LLT implementation and optimization, and LDL-C target achievement, were observed in the total STEMI population and across all very-high-risk cohorts, attributable in part to deficits in care delivery.

Background: Tei index (TI) is a combined myocardial performance index, which was found to be more sensitive for overall cardiac dysfunction than systolic or diastolic parameters alone. Currently, there is only limited evidence for this measure in the context of myocarditis. Thus, TI could add additional benefits to conventional diagnostic workup. Methods: TI of patients with myocarditis (n = 40), acute coronary syndrome (n = 29) and controls (n = 50) was retrospectively analyzed concerning its discriminatory ability for myocarditis. Results: TI was most pathological in patients with myocarditis (median 0.41 vs. 0.35 vs. 0.31, p < 0.0001). Its discriminatory ability was better than that of EF or E/e’ (AUCs: TI: 0.71, p < 0.0001; EF: 0.57, p = 0.112; E/e’: 0.64, p = 0.983), which was also verified in logistic regression analysis (B(SE) = 0.81(0.23), p = 0.0004). The association of TI with myocarditis remained significant even after correction for confounders in propensity score weighted analysis. Conclusions: The TI showed a better discriminatory ability for myocarditis than conventional echocardiographic parameters. Since TI is easily conducted, it might be a helpful adjunctive tool to supplement conventional diagnostic modalities in patients with suspected myocarditis.

Introduction: Takotsubo cardiomyopathy (TTC) and acute coronary syndrome (ACS) are clinically indistinguishable from each other. Although therapeutically redundant, coronary angiography remains indispensable for differential diagnosis. Methods: In our study, we compared hemogram parameters and their ratios in 103 patients presenting with undiagnosed chest pain. Blood was drawn at baseline in 40 patients with TTC, 63 patients with ACS, and 68 healthy controls ((Ctrl) no coronary artery disease or signs of heart failure). Results: Peripheral lymphocyte counts were significantly depressed in TTC and ACS patients when compared to the Ctrl. Consequently, all three investigated hemogram ratios were significantly elevated in patients with ACS or TTC (NLR: TTC: median 3.20 vs. ACS: median 3.82 vs. Ctrl: median 2.10, p < 0.0001; BLR: median 0.02 vs. ACS: median 0.00 vs. Ctrl: median 0.00, p < 0.0001; MLR: median 0.37 vs. ACS: median 0.44 vs. Ctrl: median 0.28, p < 0.0001). Of note, BLR was only significantly elevated in patients with TTC, and not in patients with ACS (ACS vs. Ctrl p = 0.183). Conclusion: Basophil count and BLR are significantly increased in TTC patients when compared to ACS and may, therefore, be helpful in the distinction of TTC from ACS. Whereas NLR might be useful to differentiate ACS from controls. Elevated basophil counts and BLR in TTC patients are interesting findings and may confirm speculations about the partly unexplained pathophysiology.

(1) Background: Myocarditis following group A streptococcal pharyngitis and tonsillitis is a relatively rare medical condition. The aim of this systematic review was to identify specific ECG changes, laboratory parameters and signs, and symptoms associated with this disease. (2) Methods: A systematic literature review was performed in concordance with the current PRISMA guidelines, including the databases PubMed/MEDLINE, Web of Science, CDSR, CENTRAL, CCAs, EBM Reviews, and LILACS. Articles were included if they covered myocarditis after streptococcal pharyngitis/tonsillitis in humans. Exclusion criteria were rheumatic, autoimmune, or toxic myocarditis. (3) Results: Patients that developed myocarditis after group A streptococcal throat infection frequently presented with chest pain, elevated cardiac markers, and ST-segment elevations, making it a condition that shows more similarities to acute coronary syndrome than viral myocarditis. (4) Conclusions: Myocarditis after streptococcal pharyngitis and/or tonsillitis is a rather infrequently described disease; however, it is necessary to consider this condition when investigating streptococcal sore throat because it can be associated with severe adverse events for the individual patient.

Background: Previous animal studies reported an association of non-steroidal anti-inflammatory drugs (NSAIDs) with adverse outcomes in acute myocarditis, which is why these drugs are currently not recommended in affected patients. In this retrospective case-control study, we sought to investigate the effects of NSAID treatment in patients with acute myocarditis and myopericarditis to complement the available evidence. Method: A total of 114 patients with acute myocarditis were retrospectively enrolled. Demographical, clinical and laboratory data were extracted from hospital records. Patients who received NSAIDs (n = 39, 34.2%) were compared to controls. Follow-up on all-cause mortality was acquired for two years. Propensity score matching was additionally conducted to account for covariate imbalances between groups. Results: Treatment with NSAIDs was neither associated with a worse outcome (p = 0.115) nor with significant differences in left ventricular systolic function (p = 0.228) or in-hospital complications (p = 0.507). Conclusion: Treatment with NSAIDs was not associated with adverse outcomes in our study cohort. Together with the findings of previous studies, our results indicate that these drugs could be safely administered in patients with myocarditis and myopericarditis.
