Differentiating Origins of Outflow Tract Ventricular Arrhythmias: The Correction of Transitional Zone Index Is Not Superior to the Original One.

Introduction: Our team once proposed a correction of transitional zone index (CTZI) based on the transitional zone index (TZI) in view of achieving a more precise prediction of outflow tract ventricular arrhythmia (OTVA). The predictive accuracy of these two electrocardiogram (ECG) algorithms has not been validated and compared. The purpose of this study was to compare the predictive accuracy of TZI and CTZI in a much larger population with idiopathic OTVA.

Simple Renal Cysts Are Associated With 24-Month Prognosis of Patients With Type B Aortic Dissection and Hypertension.

Background: The association of simple renal cyst (SRC) with type B aortic dissection (BAD) has recently been established. However, no studies have examined adverse events after BAD hospitalization among patients with SRC. In this study, we assessed the prognostic value of SRC in BAD patients with hypertension after thoracic endovascular aortic repair (TEVAR).

Diastolic, but not systolic, blood pressure at admission is associated with aortic-related adverse events in type B dissection after thoracic endovascular aortic repair.

Background: Hypertension is the most important risk factor for aortic dissection. We aimed to assess the association of systolic blood pressure (SBP) and diastolic blood pressure (DBP) at admission with aortic-related adverse events (ARAE) after thoracic endovascular aortic repair (TEVAR).

Methods: All patients (n = 269) admitted with type B aortic dissection (BAD) for TEVAR were included.

Optimal blood pressure control for patients after thoracic endovascular aortic repair of type B aortic dissection.

Background: Guidelines recommend tight systolic blood pressure (SBP) control for favorable outcomes of type B aortic dissection (BAD) but are still limited by the optimal cut-off value of SBP. The purpose of this study was to evaluate the optimal cut-off value of SBP in BAD patients after thoracic endovascular aortic repair (TEVAR).

Methods: From January 2011 to April 2017, 269 consecutive patients with BAD after TEVAR were included in the study.

An electrocardiographic diagnostic model for differentiating left from right ventricular outflow tract tachycardia origin.

Introduction: Although several electrocardiographic (ECG) algorithms have been proposed for differentiating the origins of outflow tract ventricular arrhythmias, the most optimal one has not been agreed on. The purpose of this study was to establish an ECG diagnostic model based on the previous ECG algorithms.

Methods And Results: The following ECG diagnostic model, Y=-1.

Double product reflects the association of heart rate with MACEs in acute coronary syndrome patients treated with percutaneous coronary intervention.

Background: There is little information about the prognostic value of double product (DP) for acute coronary syndrome (ACS) patients treated with percutaneous coronary intervention (PCI). The aim of this study was to investigate whether DP reflects the predictive power of heart rate (HR) or systolic blood pressure (SBP) in ACS patients treated with PCI.

Methods: A total of 7590 ACS patients who had undergone PCI, free from cardiac shock, were included.

Association of Thyroid Function with Early/Mid-term Aorta-Related Adverse Events and Readmissions after Thoracic Endovascular Aortic Repair.

The prognosis of patients after thoracic endovascular aortic repair (TEVAR) is affected by several clinical characteristics. This study aimed to evaluate whether thyroid hormones predicts early (30 days) and mid-term (12 months) aorta-related adverse events (ARAE) and readmissions (ARAR) in patients after TEVAR. A total of 338 continuous patients who underwent TEVAR were included and stratified based on quartile of free thyroxine (FT4) levels examined before surgery.

The relationship between heart rate and mortality of patients with acute coronary syndromes in the coronary intervention era: Meta-analysis.

Background: Most of acute coronary syndromes (ACS) were receiving intervention treatment a high overall rate of coronary angiography in the modern medical practice.Consequently, we conduct a review to determine the heart rate (HR) on the prognosis of ACS in the coronary intervention era.

Methods: PubMed, EMBASE, MEDLINE, and the Cochrane Library was systematically searched up to May 2016 using the search terms "heart rate," "acute coronary syndrome," "acute myocardial infarction," "ST elevation myocardial infarction," "non-ST-segment elevation.
