Longitudinal hemodynamics in acute phase of treatment with labetalol in hypertensive pregnant women to predict need for vasodilatory therapy
ConclusionMaternal demographics and hemodynamic changes in the acute phase of labetalol monotherapy provide a powerful tool to identify hypertensive pregnant patients who are unlikely to have their BP controlled by this therapy and will consequently need additional vasodilatory therapy.

Energy efficiency and pulmonary artery flow after balloon pulmonary angioplasty for inoperable, chronic thromboembolic pulmonary hypertension: Analysis by phase-contrast MRI
Conclusion Analysis of PA energetics using phase-contrast MRI demonstrates that BPA improves energy loss in CTEPH. In addition, BPA responses can be predicted by PA energy status pre-treatment.

Maternal Hemodynamics in Normal Pregnancies: Reference ranges and the Role of Maternal Characteristics
ConclusionMaternal hemodynamics are significantly influenced by maternal age, height and weight. We provide USCOM‐1A®‐specific reference ranges and calculator for SV, CO and SVR in uncomplicated pregnancies that correct for maternal age, height and weight. This will enable clinical application and comparison in both uncomplicated and pathological pregnancies.

Longitudinal maternal hemodynamics in pregnancies affected by fetal growth restriction
ConclusionSerial assessment of maternal hemodynamics in high‐risk women identifies distinctive trends associated with pregnancies destined to deliver babies with birth weights < 10th and < 5th percentiles. These pregnancies have a suppressed and static maternal cardiac output and stroke volume, and have consistently raised peripheral vascular resistance. This suggests that, in women with chronic hypertension or a history of hypertensive disorder in a previous pregnancy, FGR is associated with a primary and persistent failure of maternal cardiovascular adaptation in pregnancy.

Pericardial, But Not Hepatic, Fat by CT Is Associated With CV Outcomes and Structure: The Multi-Ethnic Study of Atherosclerosis
Conclusions Pericardial fat is associated with poorer CVD prognosis and LV remodeling, independent of insulin resistance, inflammation, and CT measures of hepatic fat.

Risk factors analysis of mirror aneurysms: A multi-center retrospective study based on clinical and demographic profile of patients
Publication date: November 2017 Source:European Journal of Radiology, Volume 96 Author(s): Zhong-Qing Huang, Xin-Wei Zhou, Zhong-Jun Hou, Sui-Qiao Huang, Zhi-Hua Meng, Xian-Long Wang, Hao Yu, Lv-Jin Feng, Qiu-Jing Wang, Ping-An Li, Zhi-Bo Wen As a special subgroup of multiple intracranial aneurysms, mirror aneurysms are located bilaterally on the corresponding intracranial arteries. The current study sought to compare the clinical and demographic features of patients harboring mirror aneurysm, and to elucidate the corresponding risk factors. We performed a retrospective cohort study of 2641 intracranial aneurysms patients...

A randomized controlled trial of community health workers using patient stories to support hypertension management: Study protocol
Uncontrolled hypertension is a significant public health problem in the U.S. with about one half of people able to keep blood pressure (BP) under control. Uncontrolled hypertension leads to increased risk of stroke, heart attack, and death. Furthermore, the social and economic costs of poor hypertension control are staggering. People living with hypertension can benefit from additional educational outreach and support.

MRI-derived Regional Biventricular Function in Patients with Chronic Thromboembolic Pulmonary Hypertension Before and After Pulmonary Endarterectomy
Conclusion While biventricular resynchronization and recovery of global predominantly RV function was observed, regional circumferential function mainly improved in the lateral and inferior walls of both ventricles and regional radial function in the RV wall and septum 12 days after PEA, suggesting fibers primarily affected by myocardial stress in patients with CTEPH possibly need a relatively longer recovery time.

Maternal hemodynamics in screen positive and negative women of the ASPRE trial.
CONCLUSIONS: Patients who screen positive for impaired placentation, even if they do not develop PE or deliver SGA neonates, have pathological cardiac adaptation in pregnancy and increased risk of adverse perinatal outcome.

Acute Massive and Submassive Pulmonary Embolism: Preliminary Validation of Aspiration Mechanical Thrombectomy in Patients with Contraindications to Thrombolysis
ConclusionThe high technical and clinical success of the procedure employed in this study suggests that aspiration mechanical thrombectomy is a promising technique when used alone. More extensive prospective studies are needed to assess the feasibility of this treatment.

Echocardiographic determination of pulmonary arterial capacitance
AbstractA growing body of evidence has demonstrated that pulmonary arterial capacitance (PAC) is the strongest hemodynamic predictor of clinical outcomes across a wide spectrum of cardiovascular disease, including pulmonary hypertension and heart failure. We hypothesized that a ratio of right ventricular stroke volume (RVOT VTI) to the associated peak arterial systolic pressure (PASP) could function as a reliable non-invasive surrogate for PAC. We performed a prospective study of patients undergoing simultaneous transthoracic echocardiography and right heart catheterization (RHC) for various clinical indications. Measureme...
