Multicenter Study Observational Study
Impact of Postprocedural TIMI Flow on Long-Term Clinical Outcomes in Patients with Acute Myocardial Infarction.
This study aimed to evaluate the clinical prognostic implications of postprocedural Thrombolysis in Myocardial Infarction (TIMI) flow in acute myocardial infarction patients. A total of 2796 ST-elevation myocardial infarction (STEMI) and 1720 non ST-elevation myocardial infarction (NSTEMI) patients treated in 8 hospitals affiliated with the Catholic University of Korea and Chonnam National University Hospital were analyzed. The study populations were divided according to the final TIMI flow. ⋯ In STEMI patients, good postprocedural TIMI flow after PCI was associated with favorable clinical outcomes. And the effect of poor TIMI flow in STEMI was on death, not the components of MACE. Meanwhile, postprocedural TIMI flow had no effect on long-term outcomes in NSTEMI patients.

Bevacizumab, an inhibitor of vascular endothelial growth factor (VEGF)-A, is currently used to treat patients with ovarian or colon cancer. While several cardiovascular toxicities related to bevacizumab-containing regimens have been reported, the effect of bevacizumab on the coronary microcirculation has not been fully elucidated. ⋯ This highlights the possibility that coronary microvascular angina can be induced in patients treated with bevacizumab-containing chemotherapy. It should also be noted that nicorandil can be effective in managing microvascular angina.

Comparative Study
Three-Year Major Clinical Outcomes of Angiography-Guided Single Stenting Technique in Non-Complex Left Main Coronary Artery Diseases.
There is limited long-term comparative clinical outcome data concerning angiography- versus intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) in non-complex left main coronary artery (LMCA) disease treated with the single stenting technique in the drug-eluting stent (DES) era. The aim of this study was to investigate whether angiography-guided stenting is comparable to IVUS-guided stenting during 3-year clinical follow-up periods in patients with non-complex LM disease treated with the single stenting technique. A total of 196 patients treated with either angiography-guided (n = 74) or IVUS-guided (n = 122) PCI were included. ⋯ Finally, MACE was not significantly different between the two groups (HR: 0.63, 95% Confidence interval (CI): 0.33-1.17; P = 0.149). Angiography-guided PCI for non-complex LMCA diseases treated with the single stenting technique showed comparable results compared with IVUS-guided PCI in reducing clinical events during 3-year clinical follow-up in the DES era. Although IVUS guided PCI is the ideal strategy, angiography-guided PCI can be an option for LMCA PCI in some selected cases.

A 59-year-old Japanese woman was admitted to a nearby hospital with dyspnea and general malaise. Transthoracic echocardiography revealed right ventricular (RV) dilatation with severely reduced systolic function and leftward shift of the intraventricular septum. She was initially diagnosed with acute right heart failure, and fell into cardiogenic shock requiring an intra-aortic balloon pump and inotropic agents. ⋯ She became free of symptoms and follow-up echocardiography showed normal cardiac function 3 months after the initiation of corticosteroid treatment. In addition, EMB and PET/CT showed no inflammation. This is the first case report of fulminant and right-sided dominant eosinophilic myocarditis successfully treated with corticosteroid.

We hypothesized that the effects of adaptive servo-ventilation (ASV) therapy were influenced by right-sided heart performance. This study aimed to clarify the interaction between the effects of ASV and right-sided heart performance in patients with stable heart failure (HF) with reduced ejection fraction (HFrEF). Twenty-six stable HF inpatients (left ventricular ejection fraction < 0.45, without moderate to severe mitral regurgitation (MR) were analyzed. ⋯ Although no significant differences were found in the baseline characteristics and blood tests, there were significant differences in tricuspid lateral annular systolic velocity, TAPSE, right atrial area, and right ventricular (RV) area before ASV between patients with TAPSE ≤ 16.5 mm and those with TAPSE > 16.5 mm. Interestingly, ASV reduced RV area and increased TAPSE in patients with TAPSE ≤ 16.5 mm, while it reduced TAPSE in those > 16.5 mm. ASV therapy has the potential to increase SVI in stable HFrEF patients with low TAPSE.
