Preeclampsia predicts risk of hospitalization for heart failure with preserved ejection fraction.
Preeclampsia is associated with increased risk of future heart failure (HF), but the relationship between preeclampsia and HF subtypes are not well-established. The objective of this analysis was to identify the risk of HF with preserved ejection fraction (HFpEF) following a delivery complicated by preeclampsia/eclampsia. The investigators concluded that preeclampsia/eclampsia was an independent risk factor for future hospitalizations for HFpEF.

Predictors and outcomes of heart block during surgical stage I palliation of patients with a single ventricle: a report from the NPC-QIC.
This study investigated patient and surgical risks of heart block and its effect on 12-month transplant-free survival in children with a single ventricle. In total, 1423 patients were identified from the National Pediatric Cardiology Improvement Collaborative with and without heart block. One-year outcomes were analyzed. A very small percentage (2%) developed heart block during their surgical admission. Associated risk factors for block included heterotaxy syndrome and atrial flutter/fibrillation. Patients with complete heart block had lower 12-month survival, which wasn’t true for patients with second degree block. At 12 months of age, 43% of patients with heart block died and were more likely to experience mortality than patients without heart block.

Association between troponin I levels during sepsis and postsepsis cardiovascular complications.
This study examined whether there is an association between elevated serum troponin levels and increased risk for postsepsis cardiovascular complications in patients who had been admitted for sepsis without preexisting cardiovascular disease within 5 years in adults 40 years and older. The patients were admitted with sepsis across 21 hospitals from 2011 to 2017. Peak serum troponin I levels during sepsis were grouped as normal, or tertiles of abnormal from a low of 0.04 to 0.43 ng/ml. Among 14,046 eligible adults, 10.9% had normal troponin levels, as compared to 17.3% at tertile 1, 17.6% at tertile 2, and 20.3% at tertile 3. Patients within the elevated troponin tertiles had increased risks of adverse cardiovascular events.

Depression as a risk factor for incident ischemic stroke among HIV-positive veterans in the veterans aging cohort study.
Background HIV infection and depression are each associated with increased ischemic stroke risk. Whether depression is a risk factor for stroke within the HIV population is unknown. In this study the investigators examined depression as a risk factor for incident ischemic stroke among HIV-positive veterans in the veterans aging cohort study. The investigators concluded that depression is associated with an increased risk of stroke among HIV-positive people after adjusting for sociodemographic characteristics, traditional cerebrovascular risk factors, and HIV-specific factors.

Poor weight recovery between stage 1 palliation and hospital discharge for infants with single ventricle physiology: an analysis of the NPC-QIC Phase II dataset.
The purpose of this study was to investigate change in weight-for-age z-scores (WAZ) and risk factors for impaired weight gain between stage 1 palliation (S1P) for single ventricle physiology and discharge. Data from the National Pediatric Cardiology Quality Improvement Collaborative Phase II database was analysed. Findings showed that nearly all infants lost weight after S1P, with little recovery by hospital discharge. At discharge, three-quarters of the infants were at-risk for impaired weight gain or had failure to thrive. Most risk factors associated with change in WAZ were unmodifiable or surrogates of disease severity.

A machine learning model for identifying patients at risk for wild-type transthyretin amyloid cardiomyopathy.
Transthyretin amyloid cardiomyopathy, an often-unrecognized cause of heart failure, is now treatable with a transthyretin stabilizer. It is therefore important to identify at-risk patients who can undergo targeted testing for earlier diagnosis and treatment, prior to the development of irreversible heart failure. In this study, the investigators showed that a random forest machine learning model could identify potential wild-type transthyretin amyloid cardiomyopathy using medical claims data.

Age-related trajectories of cardiovascular risk and use of aspirin and statin among U.S. Adults Aged 50 or older, 2011-2018.
The purpose of this study was to examine age-related trajectories of cardiovascular risk and use of aspirin and statin among U.S. adults aged 50 or older. The investigators concluded that while adults aged ≥75 do not benefit from the use of aspirin to prevent the first CVD, many continue to take aspirin on a regular basis. In spite of the clear benefit of statin use to prevent a subsequent CVD event, many older adults in this risk category are not taking a statin.

Barriers to implementing cardiovascular risk calculation in primary care: alignment with the consolidated framework for implementation research.
The uptake of cardiovascular disease risk calculators in primary care has been slow despite the recommendation in national cardiovascular disease prevention guidelines. Identifying the barriers to the implementation of cardiovascular disease risk calculators is essential for promoting their adoption. In this study, the authors qualitatively analyzed structured physician educator notes written during an outreach education intervention with 44 small- and medium-sized primary care clinics that participated in the Agency for Healthcare Research and Quality‒funded EvidenceNOW Healthy Hearts Northwest trial.

Risk factors associated with 30-day hospital readmission after carotid endarterectomy.
This study looked at the risk factors associated with 30-day hospital readmission after carotid endarterectomy. Patients in the Cerner Health Facts® database were selected using ICD-9-CM procedure codes. A total of 5257 patients were identified who had undergone elective carotid endarterectomy. Readmission was associated with end-stage renal disease, hemorrhage or hematoma, procedural complications, use of bronchodilators, electrolyte abnormalities, and hypokalemia less than 3.7 mEq/L. Although protamine reduces the risk of bleeding complications, only 40% of patients received that medication.

Risk of kidney failure, death, and cardiovascular events after lower limb complications in patients with CKD.
Investigators sought to determine how interim lower limb complications modify the subsequent risk of progression to kidney failure, all-cause mortality before kidney failure, and cardiovascular events in a cohort of patients with chronic kidney disease (CKD) stages G3 to G5. Patient-level data obtained from several administrative databases from Manitoba, Canada, were analyzed. They found that interim lower limb complications were associated with an increased risk of kidney failure, all-cause mortality before kidney failure, and cardiovascular-related hospitalization. They stated that clinical trials of screening and treatment strategies for patients with CKD at risk for lower limb complications may help determine optimal strategies to manage this risk.

Complex relationship between low albumin level and poor outcome after lower extremity procedures for peripheral artery disease.
Researchers sought to examine the association of low albumin level with outcomes in patients undergoing open and endovascular lower extremity procedures for peripheral artery disease. Subjects were patients with peripheral artery disease undergoing lower extremity procedures, selected from Cerner Health Facts database using ICD-9 diagnosis and procedure codes. They found that low preoperative albumin levels were associated with in-hospital death, prolonged length of stay, and severe morbidity after open and endovascular lower extremity procedures. They recommended that elective procedures be deferred until albumin levels have been optimized.

Outcomes of carotid endarterectomy versus stenting in comparable medical risk patients.
The purpose of this study was to compare risk-stratified outcomes of carotid artery stenting (CAS) and carotid endarterectomy (CEA). Included in the study group were 11,336 patients who underwent isolated primary CEA and 544 who underwent primary CAS. The researchers found that asymptomatic normal- and high-risk patients do equally well after CEA or CAS. However, normal- and high-risk symptomatic patients have substantially worse outcomes with CAS compared with CEA.

Over-the-counter and prescription sleep medication and incident stroke: the REasons for Geographic and Racial Differences in Stroke study.
The authors investigated the relation between sleep medication use and incident stroke. At the sleep assessment, 9.6% of the participants used prescription sleep medication and 11.1% used over-the-counter sleep aids. Over an average follow-up of 3.3 ± 1.0 years, 297 stroke events occurred. The authors found that over-the-counter sleep medication use was associated with increased risk of incident stroke; however, there was no significant association with prescription sleep medications. They concluded that over-the-counter sleep medication use may independently increase the risk of stroke beyond other risk factors in middle-aged to older individuals with no history of stroke.

Risk of myocardial infarction in older men receiving testosterone therapy.
The purpose of this paper was to examine the risk of myocardial infarction (MI) in a population-based cohort of older men receiving intramuscular testosterone. The investigators found that older men who were treated with intramuscular testosterone did not appear to have an increased risk of MI. For men with high MI risk, testosterone use was modestly protective against MI.

Contemporary use of dual antiplatelet therapy for preventing cardiovascular events.
The authors examined dual antiplatelet therapy (DAPT) use in contemporary clinical practice after publication of the results of the landmark randomized clinical trial CHARISMA. They found that use of DAPT is modest in patients with established cardiovascular disease, for whom the CHARISMA trial suggested decreased major adverse cardiovascular events (MACEs), and prescription rates have remained stable over time; use of DAPT in patients with multiple risk factors only, for whom CHARISMA suggested that DAPT may lead to increased MACEs, was low and decreased over time.

Claims-based algorithms for identifying Medicare beneficiaries at high estimated risk for coronary heart disease events: a cross-sectional study.
The researchers sought to develop claims-based algorithms to identify individuals at high risk for coronary artery disease (CHD) and to identify low-density lipoprotein (LDL) cholesterol among statin users at high risk for CHD events. They found that despite low sensitivity, the high predictive value of their algorithm for high risk for CHD events supports the use of claims to identify Medicare beneficiaries at high risk for CHD events.
