“…Cardiac catheterization was performed within 48–72 h of hospital admission using the femoral or radial approach. Significant coronary artery disease was defined as ≥50% luminal diameter narrowing, by visual assessment, of at least one major epicardial artery ( 13 ). Myocardial bridging was diagnosed if the typical angiographic ‘milking effect’ (i.e., systolic compression and complete or partial decompression during diastole) was observed in the coronary artery ( 14 – 17 ).…”

BackgroundTakotsubo cardiomyopathy (TTC) is characterized by reversible left ventricular dysfunction, frequently precipitated by a stressful event. Despite the favorable course and good long-term prognosis, a variety of complications may occur in the acute phase of the disease. The aim of this study was to evaluate the in-hospital and long-term outcomes of a cohort of TTC patients.MethodsFifty-five patients (mean age 68.1±12 years) were prospectively followed for a mean of 69.6±32.2 months (64,635 days). In-hospital (death, heart failure, arrhythmias) and long-term events (death and recurrences) were recorded.ResultsPatients were predominantly women (87.3%) who experienced a recent stressful event (emotional or physical) and were admitted to hospital for chest pain. Eleven patients (20%) had a diagnosis of depressive disorder, and arterial hypertension was the most frequent cardiovascular risk factor. The ECG revealed ST-segment elevation in 43.6% of patients. At angiography, seven cases (12.7%) had at least one significant (≥50%) coronary artery stenosis and four patients (7.3%) had myocardial bridging of the left anterior descending artery. During hospitalization, three patients died (one from cardiac causes) and cardiovascular complications occurred in 12 patients. During follow-up, five patients died (none from cardiac causes), six patients had recurrences within the first year. Two patients had two recurrences: one after 114 days, triggered by an asthma attack as the first event, and the other after 1,850 days.ConclusionsIn TTC patients, in-hospital and long-term mortality is primarily due to non-cardiovascular causes. Recurrences are not infrequent and coronary artery disease is not an uncommon finding.

BackgroundNonculprit lesions are the major cause of future cardiovascular events. However, the natural course of nonculprit lesions and angiographic predictors of plaque progression are not well-studied. The purpose of our study was to observe the natural course of nonculprit lesions, and to identify predictors of unanticipated future events and angiographic progression in nonculprit lesions.MethodsWe analyzed 640 nonculprit lesions with a length of ≥2 mm and luminal narrowing ≥30% from 320 patients who had two serial angiographic follow-ups; 9 to 13 months post-PCI and 24 months post-PCI. The study endpoints were nonculprit-ischemia driven revascularization (IDR) and the rate of diameter stenosis (DS) progression. Those with progression of DS > 12%/year were defined as ‘rapid progressors’.ResultsDuring the median follow-up period of 737 days, 20 lesions in 20 patients (6.3%) required nonculprit-IDR. Independent predictors of nonculprit-IDR were diabetes (hazard ratio [HR] 2.93, 95% confidence interval [CI] 1.072–8.007, p = 0.036) and lesion type B2/C (HR 4.017, 95% CI 1.614–9.997, p = 0.003). The presence of one or both of the two major risk factors was associated with significant DS progression (3.0 ± 6.8% vs. 3.5 ± 6.1% vs. 6.8 ± 9.9% for lesions with 0, 1 and both risk factors, p < 0.001). Among the 640 lesions, 38 lesions (5.9%) in 33 patients were rapid progressors, while risk factors of rapid progressors included lesion type B2/C as a lesion-related risk factor (HR 1.998, 95% CI 1.006–3.791, p = 0.048) and diabetes mellitus as a patient-related risk factor (HR 3.725, 95% CI 1.937–7.538, p < 0.001). Lesions with both risk factors (type B2/C lesions in diabetic patients) were at the highest risk of rapid progression (odds ratio 3.250, 95% CI 1.451–7.282), compared to type A/B1 lesions in non-diabetic patients.ConclusionNonculprit-IDR was not uncommon during the 2-year follow up period in our population. The major risk factors of nonculprit lesion progression were diabetes and lesion type B2/C.Trial registrationRetrospectively registered and approved by the institutional review board of Seoul National University Hospital (No.: 1801–138-918) on February 2nd, 2018.Electronic supplementary materialThe online version of this article (10.1186/s12872-018-0870-9) contains supplementary material, which is available to authorized users.
