Purpose Of Review: Obstructive sleep apnea (OSA) and hypertension are highly prevalent and treatable conditions that often coexist and both contribute to an increased cardiovascular risk. The ability of continuous positive airway pressure (CPAP) to improve blood pressure in hypertensive patients with OSA is debated. This review highlights findings from recent studies that have investigated the impact of CPAP on blood pressure in patients with OSA.
Recent Findings: Comparing the results of various studies is complicated by important methodological differences among them. In hypertensive patients with OSA, treatment with CPAP improves blood pressure to a smaller degree than that derived from antihypertensive medication. Patients with more severe OSA and with greater adherence to CPAP are likely to gain the most benefit from the therapy.
Summary: CPAP should be used in combination with antihypertensive medications in hypertensive patients with OSA. CPAP has the additional benefits of restoring nocturnal dipping and improving arterial stiffness, thus potentially influencing cardiovascular morbidity in these high-risk patients.

Efficacy of bolus injections of landiolol hydrochloride as premedication in coronary artery CT angiography.

Purpose: To assess the efficacy of bolus injections of landiolol hydrochloride as premedication in coronary artery CT angiography (CCTA).
Methods: The study population consisted of 37 patients (17 female; median age, 56 years; IQR, 19 years; range, 19-88 years) who underwent CCTA after intravenous injection of landiolol hydrochloride due to a heart rate > 60 bpm. Landiolol hydrochloride was administered in a stepwise manner until a heart rate of ≤ 60 bpm was achieved or a maximum dose of 60 mg was reached after six injections.
High variability in the reproducibility of key hemodynamic responses to head-up tilt.

Increased blood pressure upon standing is considered a cardiovascular risk factor. We investigated the reproducibility of changes in aortic blood pressure, heart rate, stroke volume, cardiac output, and systemic vascular resistance during three passive head-up tilts (HUT) in 223 participants without cardiovascular medications (mean age 46 years, BMI 28 kg/m2, 54% male). Median time gap between the first and the second HUT was 9 weeks and the second and the third HUT 4 weeks.

Metabolic indices significantly impact cardiovascular health. Research on the influence of metabolic indices on resting pulse rate in younger adults is needed. Utilizing the National Longitudinal Study of Adolescent to Adult Health (Add Health) Wave 5 Public-use biological data, we performed a multiple linear regression analysis to determine the predictive factors of resting pulse rate in adults aged 32-42 years.

Aims: A cardiovascular magnetic resonance (CMR) approach to non-invasively estimate left ventricular (LV) filling pressure was recently developed and shown to correlate with invasively measured pulmonary capillary wedge pressure (PCWP). We examined the association between CMR-estimated PCWP (CMR-PCWP) and other imaging and biomarker measures of congestion, and the effect of empagliflozin on these, in the SUGAR-DM-HF trial (NCT03485092).
Methods And Results: SUGAR-DM-HF enrolled 105 patients with heart failure with reduced ejection fraction (HFrEF) and pre-diabetes or type 2 diabetes who were randomly assigned to empagliflozin 10 mg or placebo once daily for 36 weeks.
Metabolic Status and Hypertension: The Impact of Insulin Resistance-Related Indices on Blood Pressure Regulation and Hypertension Risk.

Background: Diabetes is closely related to hypertension, and insulin resistance-related indices are novel metrics used to evaluate the risk of diabetes and cardiovascular diseases. This study aims to explore the relationships between the TyG index, METS-IR, TG/HDL-C, and HOMA-IR with hypertension.
Methods: Data from the NHANES spanning ten consecutive survey cycles from 1998 to 2018 were utilized, focusing on adults with complete blood pressure data and comprehensive information for calculating the TyG index, METS-IR, TG/HDL-C, and HOMA-IR.
