Secondary stroke prevention after TIA or ischemic stroke
Herz. 2021 Apr 29. doi: 10.1007/s00059-021-05035-0. Online ahead of print.ABSTRACTStroke is one of the main causes of mortality and permanent disability. Secondary prevention of stroke recurrence therefore has a high priority. Secondary prevention of ischemic stroke includes optimization of the lifestyle and diet, treatment of risk factors, such as hypertension, diabetes mellitus and hyperlipidemia, prophylaxis of recurrence with antiplatelet treatment in patients with high vascular risk and anticoagulation in atrial fibrillation. In addition, secondary prevention includes carotid surgery or stenting in selected symptomati...

Risk stratification for sudden cardiac death in patients with heart failure : Emerging role of imaging parameters
CONCLUSION: In future, risk stratification of arrhythmia and patient selection for ICD placement may rely on a multiparametric approach using combinations of imaging modalities in addition to left ventricular ejection fraction.PMID:33909114 | DOI:10.1007/s00059-021-05032-3 (Source: Herz)

Is coronary artery tortuosity a  predisposing factor for drug-eluting stent restenosis?
This study aimed to investigate whether the severity of tortuosity in the targeted coronary segment is a predictor of stent restenosis.METHODS: The study included a total of 637 patients undergoing drug-eluting stent implantation due to stable or unstable angina and who had no native coronary artery stenosis on their last coronary angiogram. The patients were separated into two groups: 312 patients with in-stent restenosis and 325 patients without in-stent restenosis. All patients underwent computed tomography (CT) coronary angiography after invasive angiography and CAT was calculated using the computer software.RESULTS: P...

Evaluation of atrial fibrillation risk in patients with vasovagal syncope
CONCLUSION: Interatrial and intra-atrial intervals were similar in the vasovagal syncope group and the control group. However, an increase in atrial volumes and a prolongation of certain atrial electromechanical intervals were observed in patients with vasovagal syncope. These findings suggest an alteration in atrial electromechanics caused by autonomic dysfunction that can lead to subsequent atrial arrhythmias, especially atrial fibrillation.PMID:33890135 | DOI:10.1007/s00059-021-05038-x (Source: Herz)

Supraventricular arrhythmia in mitral valve prolapse : Predictive value of P-wave dispersion and atrial conduction time
CONCLUSION: In the SVA group, PWD and AEMD were increased while HRV values were decreased. Noninvasive parameters may help predict the presence and incidence of SVA during the follow-up of this group of patients.PMID:33881560 | DOI:10.1007/s00059-021-05034-1 (Source: Herz)

Perioprocedural mortality after ICD implantation
Herz. 2021 Apr 16. doi: 10.1007/s00059-021-05033-2. Online ahead of print.ABSTRACTBACKGROUND: Implantable cardioverter defibrillators (ICD) represent an established treatment in preventing sudden cardiac death in patients with indications for primary or secondary prophylaxis. As for all complex surgical procedures there remains a risk for the occurrence of complications including death also for ICD implantation. The aim of the present study was to analyze the procedure-related mortality in patients after ICD implantation using the data from the obligatory quality assurance program in North-Rhine/Westphalia.METHODS: Data of...

Speckle tracking echocardiography in severe patient-prosthesis mismatch
This study sought to assess myocardial strain using 2D-STE to determine the relationship between subclinical left ventricular (LV) dysfunction and aortic PPM in patients undergoing AVR with preserved LV ejection fraction.MATERIAL AND METHODS: We retrospectively examined all consecutive patients with isolated AVR who presented to our center from 2005 to 2018. The data of 1086 patients were analyzed. Severe PPM was defined as an indexed effective orifice area of 0.65 cm2/m2 or less. As a result of the detailed assessment, 54 patients meeting the eligibility criteria were included in the study. Baseline data were collected an...

Cardiovascular evaluation in advanced chronic kidney disease
Herz. 2021 Mar 2. doi: 10.1007/s00059-021-05028-z. Online ahead of print.ABSTRACTPatients with chronic kidney disease (CKD) display an increased cardiovascular comorbidity, which is often underdiagnosed. Thus, effective cardiovascular diagnostic testing is of particular importance for this group of patients. Data from prospective randomized trials with cardiovascular diagnostic testing in CKD patients and improved outcome are limited. Diagnostic stress testing for CKD patients requires special consideration. Guidelines recommend cardiovascular diagnostic testing for patients undergoing an evaluation before transplantation....
