Background and Objective: The pathophysiology of isolated coronary artery ectasia (CAE) remains poorly understood although associations between CAE and a broad spectrum of different diseases, especially atherosclerotic coronary artery disease have been reported. This study aimed to investigate the clinical characteristics of CAE and its relationship to obstructive artery disease in the Chinese Population. Methods and Results: This study recruited 3793 consecutive patients who had undergone coronary angiography for suspected coronary artery disease (CAD) between January 2009 and December 2014. The median age of the patients was 63 years (range, 27 to 94 years) and the majority (69.71%) was male. There were 3068 patients with obstructive coronary artery disease, including angina pectoris (n=1611), acute myocardial infarction (n=1265), and old myocardial infarction (n=192). A total of 120 cases (Male, n=93, female, n=27) with a median age of 63 years (range, 28-86) were identified as CAE in patients undergoing coronary angiography. Co-existent CAD was present in 94% of CAE patients, including 56 angina pectoris; 53 acute myocardial infarction; and 4 old myocardial infarction cases. The prevalence of CAE in patients with obstructive coronary artery disease was 3.67%. The frequency of arterial involvement was: right coronary artery (RCA), 63%; left anterior descending artery (LAD), 43%; left circumflex artery (LCX), 38%; and left main artery (LM), 14%. CAE affected only 1 major vessel in 83% of cases, 2 vessels in 12%, and all 3 vessels in 5%. Using multivariate analysis, serum levels of uric acid were independently associated with present of CAE (P<0.001), while other cardiovascular risk factors such age, arterial hypertension, dyslipidemia, smoking, and diabetes mellitus did not show statistically significant associations (P>0.05). Conclusion: The prevalence of CAE in patients with obstructive coronary artery disease was 3.67%. The RCA was the most commonly affected and most patients had single vessel involvement. Increased serum uric acid level may be a potential risk factor for presence of CAE.

Background. Takotsubo syndrome is a reversible heart failure syndrome which often presents with symptoms and ECG changes that mimic an acute myocardial infarction. Obstructive coronary artery disease has traditionally been seen as exclusion criteria for the diagnosis of takotsubo; however, recent reports have called this into question and suggest that the two conditions may coexist. Case Summary. We describe a case of an 83-year-old male presenting with chest pain consistent with acute myocardial infarction. The ECG demonstrated anterior ST elevation with bedside echocardiography showing apical wall motion abnormalities. Cardiac catheterisation found an occluded OM2 branch of the left circumflex artery with ventriculography confirming apical ballooning consistent with takotsubo and not in the vascular territory supplied by the occluded epicardial vessel. Repeat echocardiogram 6 weeks later confirmed resolution of the apical wall motion abnormalities consistent with a diagnosis of takotsubo. Discussion. This case demonstrates the finding of takotsubo syndrome in a male patient with acute myocardial infarction. Traditionally, this would preclude a diagnosis of takotsubo; however, following previous reports of takotsubo in association with coronary artery dissection and acute myocardial infarction in female patients, new diagnostic criteria have been proposed which allow the diagnosis of takotsubo in the presence of obstructive coronary artery disease. This case adds to the growing body of literature that suggests takotsubo can coexist with acute myocardial infarction; however, it remains to be elucidated if it is a consequence or cause of myocardial infarction.

Abstract: Arrhythmia is an abnormal heart rhythm which refer to every disturbance in frequency, regularity, original location or electrical impulses conduction of the heart. Ischemic myocardium characterized by ionic and biochemical alterations creates an unstable electrical substrate capable of initiating and sustaining arrhythmias, meanwhile infarction creates areas of electrical inactivity and blocks conduction, which also promotes arrhythmogenesis. This study was aimed to obtain the description of arrhythmias in coronary artery disease patients at Prof. Dr. R. D. Kandou Hospital Manado from 1 January 2015 to 31 December 2015. This was a descriptive retrospective study. There were 101 data of patients with Coronary Artery Disease (CAD) associated with arrhythmia, as follows: 57 cases (56%) of Stable Angina Pectoris (SAP), 6 cases (6%) of Old Myocardial Infarction (OMI), 16 cases (16%) of Unstable Angina Pectoris (UAP), 20 cases (20%) of Non ST Segment Elevation Myocardial Infarction (NSTEMI), and 2 cases (2%) of ST Segment Elevation Myocardial Infarction (STEMI). The majority of cases were males (66%) and aged 51-60 years old (35%). There were 62 cases (41%) of CAD patients associated with arrhythmia that had hypertension as the highest risk factor and 19 cases (12%) for smoker as the lowest risk factor. The highest number of patients was Angina Pectoris Stabil (APS), and the dominant arrhythmia was Premature Ventricular Contraction (PVC).Keywords: description, arrhythmia, coronary artery disease Abstrak: Aritmia merupakan gangguan irama jantung yang merujuk kepada setiap gangguan frekuensi, regularitas, lokasi asal atau konduksi impuls listrik jantung. Iskemik miokardium ditandai dengan perubahan ion dan biokimiawi, mengakibatkan aktivitas listrik yang tidak stabil yang memicu dan mempertahankan aritmia, dan infark menciptakan daerah aktif dan blok konduksi listrik, yang juga memromosikan aritmogenesis. Penelitian ini bertujuan untuk mengetahui gambaran aritmia pada pasien penyakit jantung koroner (PJK) di RSUP Prof. Dr. R. D. Kandou Manado periode 1 Januari 2015-31 Desember 2015. Jenis penelitian ialah deskriptif retrospektif. Hasil penelitian mendapatkan 101 data pasien PJK yang mengalami aritmia, diantaranya Angina Pektoris Stabil (APS) 57 kasus (56%), Old Myocardial Infarction (OMI) 6 kasus (6%), Unstable Angina Pectoris (UAP) 16 kasus (16%), Non ST Segment Elevation Myocardial Infarction (NSTEMI) 20 kasus (20%), dan ST Segment Elevation Myocardial Infarction (STEMI) 2 kasus (2%). Mayoritas kasus ialah jenis kelamin laki-laki (66%), usia 51-60 tahun (35%). Faktor risiko tertinggi pada pasien PJK dengan aritmia ialah hipertensi (41%) dan terendah ialah merokok (12%). Kasus tertinggi ialah APS, dengan aritmia terbanyak ialah Premature Ventricular Contraction (PVC), Kata kunci: gambaran, aritmia, penyakit jantung koroner

Abstract Funding Acknowledgements Type of funding sources: None. Background. In recent years a group of patients with acute myocardial infarction without obstructive coronary artery disease (MINOCA) is of interest. In this group of patients, there is a lack of information related to myocardial perfusion, blood flow and reserve, which could be important in term of risk and prognosis assessment. Purpose. To assess the visual and quantitative MPS SPECT parameters in MINOCA patients compared to cardiac magnetic resonance (CMR) data. Methods.  In the period from 2017 to 2018 were examined 18 (8 male, mean 62.9 ± 10.7years) consecutive patients with acute myocardial infarction without obstructive coronary artery disease (MINOCA). Within 7-10 days after admission to the hospital and one year later all patients underwent SPECT myocardial perfusion scintigraphy (MPS) with the assessment of standard indices (SSS, SRS, SDS) and quantitative parameters: rest MBF (rMBF), stress MBF (sMBF) and CFR (on CZT gamma-camera). Also, all patients underwent CMR. Based on CMR data all patient were divided into two groups: 1) patients with non-ischemic type of injury and 2) patients with ischemic type of injury. Results. We found out significant correlation between regional quantitative SPECT indices and transmural extent of myocardial infarction evaluated by CMR: r=–0.4 for sMBF; r=–0.35 for CFR (p &lt; 0.05). In the first hospitalization this groups of patient didn`t have of any differences, according visual and quantitative data by SPECT. However, in one year, visual analysis showed that SSS and SDS were significantly (p &lt; 0.001) lower in patient with ischemic type of injury by CMR data: 2 (2; 3) vs 5.5 (4; 9) and 2 (1; 3) vs 4.5 (2; 5), respectively. According to the quantitative MPS data analysis, global and CFR values were significantly lower in patients with non-ischemic type of injury 1.30 (1.14; 1.75) vs 1.71 (1.34; 1.81). Conclusion. The analysis of quantitative MPS SPECT parameters showed that such approach allows identifying MBF and CFR disturbances. These results showed that MINOCA patients are heterogeneous group and require more strong investigation, observation and treatment.
