Background: Over a 14-year period, age-adjusted high total cholesterol (≥240 mg/dL) in the United States declined from 18.3% in 1999 to 2000 to 11.0% in 2013 to 2014, coinciding with the 2001 National Cholesterol Education Program Adult Treatment Panel (ATP)-III guidelines that endorsed low-density lipoprotein (LDL)-cholesterol blood value goals. Statin treatment recommendations were revised by the American College of Cardiology and the American Heart Association (ACC/AHA) in November 2013 to a "risk-based prescription" approach that did not utilize blood cholesterol values. This increased dosage and expanded the statin-eligible population by an estimated 12.8 million US adults. These changes should further lower total and LDL cholesterol concentrations nationally.
Methods: We examined data from 507 752 patients nationally aged ≥16 years whose fasting bloods were sent to Boston Heart Diagnostics for direct LDL-cholesterol measurements. Between 2012 and 2017, age-adjusted concentrations were examined by analysis of covariance and LDL-cholesterol ≥160 mg/dL by logistic regression.
Results: Contrary to expectations, age-adjusted mean LDL-cholesterol concentrations (±SE, mg/dL) increased significantly (P < 10 ) in men (2012:113.8 ± 0.3; 2013:115.3 ± 0.2; 2014:114.7 ± 0.2; 2015:116.0 ± 0.2; 2016:117.6 ± 0.2; and 2017:117.1 ± 0.2 mg/dL) and women (2012:119.5 ± 0.3; 2013:120.7 ± 0.2; 2014:119.8 ± 0.02; 2015:120.8 ± 0.2; 2016:122.7 ± 0.1; and 2017:123.8 ± 0.2 mg/dL). The percentage with LDL-cholesterol ≥160 mg/dL also increased significantly (P < 10 ) in men and women. Similar results were obtained for ages 40 to 75 years olds (corresponding to ACC/AHA guidelines).
Conclusion: These results provide additional evidence that declining blood LDL-cholesterol levels observed following the ATP-III recommendations, did not further decline (actually increased) following the 2013 ACC/AHA recommendations.

Background: Cardiogenic shock (CS) is a heterogeneous clinical syndrome, making it challenging to predict patient trajectory and response to treatment. This study aims to identify biological/molecular CS subphenotypes, evaluate their association with outcome, and explore their impact on heterogeneity of treatment effect (ShockCO-OP, NCT06376318).
Methods: We used unsupervised clustering to integrate plasma biomarker data from two prospective cohorts of CS patients: CardShock (N = 205 [2010-2012, NCT01374867]) and the French and European Outcome reGistry in Intensive Care Units (FROG-ICU) (N = 228 [2011-2013, NCT01367093]) to determine the optimal number of classes.
Diabetes is associated with a higher incidence of short-term mortality risk and readmission in patients who undergo surgical but not transcatheter aortic valve replacement.

Background: Transcatheter aortic valve replacement (TAVR) is increasingly used for aortic valve replacement instead of surgical aortic valve replacement (sAVR). We aimed to examine the impact of diabetes on 30-day mortality, 30-day readmission and compare outcomes between TAVR and sAVR.
Methods: Data were extracted from the Nationwide Readmissions Database from 2012 to 2017.

Obstructive sleep apnea (OSA) often leads to complications in the elderly. This study compares the usefulness of five screening tools for OSA in elderly patients. Data from elderly patients diagnosed with OSA, collected from the Sleep Medicine Center of the First Affiliated Hospital of Guangzhou Medical University from January 2012 to June 2017, is analyzed.

Background And Objective: Fexofenadine is commonly used as a probe substrate to assess P-glycoprotein (Pgp) activity. While its use in healthy volunteers is well documented, data in older adult and polymorbid patients are lacking. Age- and disease-related physiological changes are expected to affect the pharmacokinetics of fexofenadine.
