Effect of Smaller Left Ventricular Capture Threshold Safety Margins to Improve Device Longevity in Recipients of Cardiac Resynchronization-Defibrillation Therapy

Nov 28, 2016 by in CARDIOLOGY Comments Off on Effect of Smaller Left Ventricular Capture Threshold Safety Margins to Improve Device Longevity in Recipients of Cardiac Resynchronization-Defibrillation Therapy

Device longevity in cardiac resynchronization therapy (CRT) is affected by the pacing capture threshold (PCT) and programmed pacing amplitude of the left ventricular (LV) pacing lead. The aims of this…

Usefulness of an Echocardiographic Composite Cardiac Calcium Score to Predict Death in Patients With Stable Coronary Artery Disease (from the Heart and Soul Study)

Nov 28, 2016 by in CARDIOLOGY Comments Off on Usefulness of an Echocardiographic Composite Cardiac Calcium Score to Predict Death in Patients With Stable Coronary Artery Disease (from the Heart and Soul Study)

Mitral annular calcium and aortic valve sclerosis on transthoracic echocardiography (TTE) are independently associated with cardiovascular (CV) events in patients with coronary artery disease (CAD). However, the prognostic value of…

Risk of Mortality Associated With QT and JT Intervals at Different Levels of QRS Duration (from the Third National Health and Nutrition Examination Survey)

Nov 28, 2016 by in CARDIOLOGY Comments Off on Risk of Mortality Associated With QT and JT Intervals at Different Levels of QRS Duration (from the Third National Health and Nutrition Examination Survey)

QT prolongation in the setting of QRS >120 ms is believed to be triggered by prolonged depolarization rather than repolarization. Hence, JT interval is suggested as an alternative to QT interval…

Comparative Effectiveness of Cardiac Resynchronization Therapy Defibrillators Versus Standard Implantable Defibrillators in Medicare Patients

Nov 28, 2016 by in CARDIOLOGY Comments Off on Comparative Effectiveness of Cardiac Resynchronization Therapy Defibrillators Versus Standard Implantable Defibrillators in Medicare Patients

Previous analyses have shown that there is lower mortality with cardiac resynchronization therapy defibrillators (CRT-D) in patients with left bundle branch block (LBBB) but demonstrated mixed results in patients without…

Comparison of Five-Year Outcome of Percutaneous Coronary Intervention With Coronary Artery Bypass Grafting in Triple-Vessel Coronary Artery Disease (from the Coronary Revascularization Demonstrating Outcome Study in Kyoto PCI/CABG Registry Cohort-2)

Nov 28, 2016 by in CARDIOLOGY Comments Off on Comparison of Five-Year Outcome of Percutaneous Coronary Intervention With Coronary Artery Bypass Grafting in Triple-Vessel Coronary Artery Disease (from the Coronary Revascularization Demonstrating Outcome Study in Kyoto PCI/CABG Registry Cohort-2)

Studies evaluating long-term (≥5 years) outcomes of percutaneous coronary intervention (PCI) using drug-eluting stents compared with coronary artery bypass grafting (CABG) in patients with triple-vessel coronary artery disease (TVD) are…

Comparison of Contrast Volume, Radiation Dose, Fluoroscopy Time, and Procedure Time in Previously Published Studies of Rotational Versus Conventional Coronary Angiography

Nov 28, 2016 by in CARDIOLOGY Comments Off on Comparison of Contrast Volume, Radiation Dose, Fluoroscopy Time, and Procedure Time in Previously Published Studies of Rotational Versus Conventional Coronary Angiography

Conventional coronary angiography (CA) with static imaging is limited by the ability to properly select the optimal acquisition angle, vessel foreshortening, and significant radiation exposure. Rotational coronary angiography (RA) acquires…

Diagnostic and Therapeutic Usefulness of Coronary Computed Tomography Angiography in Out-Clinic Patients Referred for Chest Pain

Nov 28, 2016 by in CARDIOLOGY Comments Off on Diagnostic and Therapeutic Usefulness of Coronary Computed Tomography Angiography in Out-Clinic Patients Referred for Chest Pain

Coronary computed tomography angiography (CCTA) is widely used to exclude coronary artery disease (CAD) in patients with low-to-intermediate pretest probability (PTP) of obstructive CAD. The aim of our study was…

Balancing the Risk of Bleeding and Stroke in Patients With Atrial Fibrillation After Percutaneous Coronary Intervention (from the AVIATOR Registry)

Nov 28, 2016 by in CARDIOLOGY Comments Off on Balancing the Risk of Bleeding and Stroke in Patients With Atrial Fibrillation After Percutaneous Coronary Intervention (from the AVIATOR Registry)

Patients with atrial fibrillation (AF) who underwent percutaneous coronary intervention (PCI) are at elevated risk for bleeding and thromboembolic ischemic events. Currently, guidelines on antithrombotic treatment for these patients are…

Long-Term Outcomes After Coronary Stent Implantation in Patients Presenting With Versus Without Acute Myocardial Infarction (an Observation from Coronary Revascularization Demonstrating Outcome Study-Kyoto Registry Cohort-2)

Nov 28, 2016 by in CARDIOLOGY Comments Off on Long-Term Outcomes After Coronary Stent Implantation in Patients Presenting With Versus Without Acute Myocardial Infarction (an Observation from Coronary Revascularization Demonstrating Outcome Study-Kyoto Registry Cohort-2)

It has not been adequately addressed yet how long the excess cardiovascular event risk persists after acute myocardial infarction (AMI) compared with stable coronary artery disease. Of 10,470 consecutive patients…
