p.Arg4810Lys is linked to various vascular diseases, including pulmonary arterial hypertension (PAH); however, its pathogenesis remains unclear. Here, we report the unique features of two cases of severe PAH with this variant: one is the first reported case with stenosis of the thoracic and abdominal aorta, femoral arteries, and subclavian veins. Coexistence of severe and continuous eosinophilic inflammation, which has been suspected to be implicated in the pathogenesis of PAH in previous fundamental studies, was also present in both cases. Further studies are needed to clarify the pathogenetic mechanisms in vascular lesions with this variant.

We evaluated the systemic cardiovascular and carotid baroreflex support of arterial pressure during recovery from whole-body, passive heating in young and older adults. Supine mean arterial pressure (MAP), cardiac output (Q; acetylene washin), systemic vascular conductance (SVC), heart rate (HR), and stroke volume (SV) were evaluated in 16 young (8F, 18-29 years) and nine older (6F, 61-73 years) adults at normothermic baseline and for 60-min passive heating and 120-min normothermic recovery. Externally applied neck pressure was used to evaluate HR, brachial vascular conductance, and MAP responses to carotid baroreceptor unloading.

Autosomal recessive renal tubular dysgenesis (RTD) is a rare genetic disorder caused by defects in the renin-angiotensin system, with the most common outcomes being foetal or neonatal death from renal failure, pulmonary hypoplasia and/or refractory arterial hypotension. A small proportion of patients survive past the neonatal period. We present the case of a toddler with RTD due to compound heterozygous variants in the gene that codes for ACE, who has not required renal replacement therapy to date and in whom fludrocortisone has achieved electrolyte and acid/base balance.

Background: Clinical trials typically report average health status outcomes by treatment at single points in time, as opposed to participants' trajectories (or journeys) over time. Although ISCHEMIA (International Study of Comparative Health Effectiveness with Medical and Invasive Approaches) demonstrated better mean health status at discrete times with an invasive treatment among those with baseline angina, the patterns of individual participants' angina over time are unknown.
Objectives: The purpose of this study was to identify patterns of individual participants' angina over time after invasive or conservative management strategies for chronic coronary disease.

Background: The hemodynamic effects of femoro-femoral venoarterial (VA) extracorporeal membrane oxygenation (ECMO) on pulmonary capillary wedge pressure (PCWP) remain poorly defined. High ECMO flow is believed to increase PCWP and the risk of pulmonary edema; yet, supporting in vivo physiological data are lacking.
Objectives: The purpose of this study was to evaluate the impact of incremental femoro-femoral VA-ECMO flow variations on PCWP, hemodynamic, and echocardiographic parameters in patients with cardiogenic shock during the early phase of VA-ECMO support, after stabilization.
