Percutaneous coronary intervention in cancer patients: a report of the prevalence and outcomes in the United States.

AIMS: This study aims to examine the temporal trends and outcomes in patients who undergo percutaneous coronary intervention (PCI) with a previous or current diagnosis of cancer, according to cancer type and the presence of metastases. METHODS AND RESULTS: Individuals undergoing PCI between 2004 and 2014 in the Nationwide Inpatient Sample were included in the study. Multivariable analyses were used to determine the association between cancer diagnosis and in-hospital mortality and complications. 6 571 034 PCI procedures were included and current and previous cancer rates were 1.8% and 5.8%, respectively. Both rates increased over time and the four most common cancers were prostate, breast, colon, and lung cancer. Patients with a current lung cancer had greater in-hospital mortality (odds ratio (OR) 2.81, 95% confidence interval (95% CI) 2.37-3.34) and any in-hospital complication (OR 1.21, 95% CI 1.10-1.36), while current colon cancer was associated with any complication (OR 2.17, 95% CI 1.90-2.48) and bleeding (OR 3.65, 95% CI 3.07-4.35) but not mortality (OR 1.39, 95% CI 0.99-1.95). A current diagnosis of breast was not significantly associated with either in-hospital mortality or any of the complications studied and prostate cancer was only associated with increased risk of bleeding (OR 1.41, 95% CI 1.20-1.65). A historical diagnosis of lung cancer was independently associated with an increased OR of in-hospital mortality (OR 1.65, 95% CI 1.32-2.05). CONCLUSIONS: Cancer among patients receiving PCI is common and the prognostic impact of cancer is specific both for the type of cancer, presence of metastases and whether the diagnosis is historical or current. Treatment of patients with a cancer diagnosis should be individualized and involve a close collaboration between cardiologists and oncologists.

Temporal Changes in Hypertensive Disorders of Pregnancy and Impact on Cardiovascular and Obstetric Outcomes.

Hypertensive disorders of pregnancy (HDP) are a major cause of maternal morbidity. However, short-term outcomes of HDP subgroups remain unknown. Using National Inpatient Sample database, all delivery hospitalizations between 2004 and 2014 with or without HDP (preeclampsia/eclampsia, chronic hypertension, superimposed preeclampsia on chronic hypertension, and gestational hypertension) were analyzed to examine the association between HDP and adverse in-hospital outcomes. We identified >44 million delivery hospitalizations, within which the prevalence of HDP increased from 8% to 11% over a decade with increasing comorbidity burden. Women with chronic hypertension have higher risks of myocardial infarction, peripartum cardiomyopathy, arrhythmia, and stillbirth compared to women with preeclampsia. Out of all HDP subgroups, the superimposed preeclampsia population had the highest risk of stroke (odds ratio [OR] 7.83, 95% confidence interval [CI] 6.25 to 9.80), myocardial infarction (OR 5.20, 95% CI 3.11 to 8.69), peripartum cardiomyopathy (OR 4.37, 95% CI 3.64 to 5.26), preterm birth (OR 4.65, 95% CI 4.48 to 4.83), placental abruption (OR 2.22, 95% CI 2.09 to 2.36), and stillbirth (OR 1.78, 95% CI 1.66 to 1.92) compared to women without HDP. In conclusion, we are the first to evaluate chronic systemic hypertension without superimposed preeclampsia as a distinct subgroup in HDP and show that women with chronic systemic hypertension are at even higher risk of some adverse outcomes compared to women with preeclampsia. In conclusion, the chronic hypertension population, with and without superimposed preeclampsia, is a particularly high-risk group and may benefit from increased antenatal surveillance and the use of a prognostic risk assessment model incorporating HDP to stratify intrapartum care.

Burden of 30-Day Readmissions After Percutaneous Coronary Intervention in 833,344 Patients in the United States: Predictors, Causes, and Cost: Insights From the Nationwide Readmission Database.

OBJECTIVES: This study aimed to examine the 30-day unplanned readmissions rate, predictors of readmission, causes of readmissions, and clinical impact of readmissions after percutaneous coronary intervention (PCI). BACKGROUND: Unplanned rehospitalizations following PCI carry significant burden to both patients and the local health care economy and are increasingly considered as an indicator of quality of care. METHODS: Patients undergoing PCI between 2013 and 2014 in the U.S. Nationwide Readmission Database were included. Incidence, predictors, causes, and cost of 30-day unplanned readmissions were determined. RESULTS: A total of 833,344 patients with PCI were included, of whom 77,982 (9.3%) had an unplanned readmission within 30 days. Length of stay for the index PCI was greater (4.7 vs. 3.9 days) and mean total hospital cost ($23,211 vs. $37,524) was higher for patients who were readmitted compared with those not readmitted. The factors strongly independently associated with readmissions were index hospitalization discharge against medical advice (odds ratio [OR]: 1.91; 95% confidence interval [CI]: 1.65 to 2.22), transfer to short-term hospital for inpatient care (OR: 1.62; 95% CI: 1.38 to 1.90), discharge to care home (OR: 1.57; 95% CI: 1.51 to 1.64), and chronic kidney disease (OR: 1.50; 95% CI: 1.44 to 1.55). Charlson Comorbidity Index score (OR: 1.28; 95% CI: 1.27 to 1.29) and number of comorbidities (OR: 1.18; 95% CI: 1.17 to 1.18) were independently associated with unplanned readmission. The majority of readmissions were due to noncardiac causes (56.1%). CONCLUSIONS: Thirty-day readmissions after PCI are relatively common and relate to baseline comorbidities and place of discharge. More than one-half of the readmissions were due to noncardiac causes.

The Effect of Glucagon-Like Peptide 1 Receptor Agonists on Weight Loss in Type 2 Diabetes: A Systematic Review and Mixed Treatment Comparison Meta-Analysis.

AIMS: To determine the effects of glucagon-like peptide-1 receptor agonists compared with placebo and other anti-diabetic agents on weight loss in overweight or obese patients with type 2 diabetes mellitus. METHODS: Electronic searches were conducted for randomised controlled trials that compared a glucagon-like peptide-1 receptor agonist therapy at a clinically relevant dose with a comparator treatment (other type 2 diabetes treatment or placebo) in adults with type 2 diabetes and a mean body mass index ≥ 25 kg/m2. Pair-wise meta-analyses and mixed treatment comparisons were conducted to examine the difference in weight change at six months between the glucagon-like peptide-1 receptor agonists and each comparator. RESULTS: In the mixed treatment comparison (27 trials), the glucagon-like peptide-1 receptor agonists were the most successful in terms of weight loss; exenatide 2 mg/week: -1.62 kg (95% CrI: -2.95 kg, -0.30 kg), exenatide 20 µg: -1.37 kg (95% CI: -222 kg, -0.52 kg), liraglutide 1.2 mg: -1.01 kg (95%CrI: -2.41 kg, 0.38 kg) and liraglutide 1.8 mg: -1.51 kg (95% CI: -2.67 kg, -0.37 kg) compared with placebo. There were no differences between the GLP-1 receptor agonists in terms of weight loss. CONCLUSIONS: This review provides evidence that glucagon-like peptide-1 receptor agonist therapies are associated with weight loss in overweight or obese patients with type 2 diabetes with no difference in weight loss seen between the different types of GLP-1 receptor agonists assessed.
