Safety and Efficacy of Periprocedural Heparin Plus a Short-Term Infusion of Tirofiban Versus Bivalirudin Monotherapy in Patients Who Underwent Percutaneous Coronary Intervention (from the Intermountain Heart Institute STAIR Observational Registry).

Am J Cardiol 2019 Mar 16. Epub 2019 Mar 16.

Department of Cardiology, Intermountain Heart Institute, Murray, Utah.

Glycoprotein IIb/IIIa inhibitors, used as a standard intravenous bolus followed by a prolonged infusion for 12 to 18 hours, reduces ischemic complications during percutaneous coronary interventions (PCI) but often at a cost of increased bleeding. Today, when dual oral antiplatelet therapy is routine, heparin use plus short-term (bolus alone or with a <6 hours infusion) glycoprotein IIb/IIIa inhibitors, or bivalirudin monotherapy, have been proposed as potentially superior alternatives. This observational study evaluated the safety and efficacy of heparin plus short-term tirofiban versus bivalirudin monotherapy during PCI. Read More

Usefulness of a Positive Psychology-Motivational Interviewing Intervention to Promote Positive Affect and Physical Activity After an Acute Coronary Syndrome.

Am J Cardiol 2019 Mar 19. Epub 2019 Mar 19.

Harvard Medical School, Boston, Massachusetts; Department of Psychiatry, Massachusetts General Hospital, Boston, Massachusetts.

Most patients are not able to achieve recommended levels of physical activity following an acute coronary syndrome (ACS). Existing interventions to promote activity have not focused on promoting psychological well-being, which is independently linked to superior cardiac health. To address this gap, we developed and tested a combined positive psychology-motivational interviewing (PP-MI) intervention in post-ACS patients to assess its feasibility and explore potential benefits in an initial randomized trial.

Usefulness of Predischarge Cardiac Testing in Low Risk Women and Men for Safe, Rapid Discharge from a Chest Pain Unit.

Am J Cardiol 2019 Mar 8. Epub 2019 Mar 8.

Division of Cardiovascular Medicine, University of California Davis Health, Sacramento, California.

Predischarge cardiac testing (PDT) in low-risk patients evaluated for acute coronary syndrome in a chest pain unit (CPU) remains a challenge. It is unclear whether PDT varies by gender. We analyzed consecutive low-risk women and men evaluated in our CPU over a 2-year period and compared the utilization of PDT (exercise treadmill test, myocardial stress perfusion scintigraphy, exercise stress echocardiography, invasive coronary angiography, or no test), and incidence of major adverse cardiac events (MACE) at 30days and 6 months.

Usefulness of Inferior Vena Cava Filters in Stable Patients with Acute Pulmonary Embolism.

Am J Cardiol 2019 Mar 14. Epub 2019 Mar 14.

Department of Osteopathic Medical Specialties, College of Osteopathic Medicine, Michigan State University, East Lansing, Michigan.

Retrospective cohort studies using administrative data from national databases or a registry suggest that there are subcategories of stable patients with acute pulmonary embolism who would show a reduced mortality with an inferior vena cava (IVC) filter in addition to anticoagulants. These subcategories are those who underwent pulmonary embolectomy, receiving thrombolytic therapy, suffering recurrent pulmonary embolism while on treatment, hospitalized with solid malignant tumors if aged >60years, hospitalized with chronic obstructive pulmonary disease (COPD) if aged >50years, and very elderly (aged >80 years). The following is a review of these studies. Read More

Prevalence of Coronary Vasospasm Using Coronary Reactivity Testing in Patients With Spontaneous Coronary Artery Dissection.

Am J Cardiol 2019 Mar 9. Epub 2019 Mar 9.

Department of Cardiovascular Medicine, Heart and Vascular Institute, Cleveland Clinic, Cleveland, Ohio. Electronic address:

Spontaneous coronary artery dissection (SCAD) is an important cause of myocardial infarction and sudden cardiac death, particularly in young to middle-aged women. Coronary vasospasm is another condition believed to be associated with SCAD; however, this has only been shown in isolated case reports to date. We sought to examine the association of SCAD and coronary vasospasm by reporting the experience of coronary vasospasm testing in patients with a history of previous SCAD in a large, tertiary referral center.

Relation of Cardiovascular Events and Deaths to Low-Density Lipoprotein Cholesterol Level Among Statin-Treated Patients With Atherosclerotic Cardiovascular Disease.

Am J Cardiol 2019 Mar 8. Epub 2019 Mar 8.

Amgen, Inc., Thousand Oaks, California.

This study describes subsequent cardiovascular events and deaths by low-density lipoprotein cholesterol (LDL-C) level in patients with atherosclerotic cardiovascular disease (ASCVD) receiving moderate- to high-intensity statins. Olmsted County, Minnesota residents with index ASCVD (myocardial infarction, unstable angina, coronary revascularization, ischemic stroke or transient ischemic attack) occurring between 2005 and 2012 were identified, and those with a prescription for a moderate- or high-intensity statin and an LDL-C measurement in the 90days after index were included. Cox regression models were used to examine associations between LDL-C, modeled as a time-dependent variable, and a composite outcome of subsequent cardiovascular events or all-cause death. Read More

Impact of Left Ventricular Hypertrophy on Peak Serum Troponin T Levels in Patients With Acute Myocardial Infarction.

Am J Cardiol 2019 Mar 9. Epub 2019 Mar 9.

Division of Cardiovascular Medicine, University of Missouri School of Medicine, Columbia, Missouri.

Previous studies have reported that peak serum troponin I levels were disproportionately elevated in patients with acute anterior ST-segment elevation myocardial infarction (STEMI) and left ventricular (LV) hypertrophy (LVH) compared with those with normal LV mass. The purpose of this retrospective study was to assess the relation of peak serum troponin T levels in patients with normal LV mass and in subjects with mild, moderate, and severe LVH in patients with acute STEMI or non-ST segment elevation myocardial infarction (NSTEMI) when stratified on variables that might be expected to affect serum troponin T levels. The study population consisted of 262 patients; 91 with STEMI and 161 with NSTEMI. Read More

One- to 10-Day Versus 11- to 30-Day All-Cause Readmission and Mortality in Older Patients With Heart Failure.

Am J Cardiol 2019 Mar 13. Epub 2019 Mar 13.

Veterans Affairs Medical Center, Washington, District of Columbia; George Washington University, Washington, District of Columbia; University of Alabama at Birmingham, Birmingham, Alabama. Electronic address:

Heart failure (HF) is the leading cause for 30-day all-cause readmission in older Medicare beneficiaries and 30-day all-cause readmission is associated with a higher risk of mortality. In the current analysis, we examined if that association varied by timing of 30-day all-cause readmission. Of the 8,049 Medicare beneficiaries hospitalized for HF, 1,688 had 30-day all-cause readmissions, of whom 1,519 were alive at 30 days. Read More
