Role of echocardiography and cardiac biomarkers in prediction of in-hospital mortality and long-term risk of brain infarction in pulmonary embolism patients
ConclusionsHigh blood troponin T, NT-proBNP, RV dilatation/systolic dysfunction and pulmonary hypertension predicted in-hospital mortality. PFO/RLS presence and ST were predictors of clinically apparent/silent brain infarction.

Effects of Riociguat on Right Ventricular Remodeling in Chronic Thromboembolic Pulmonary Hypertension Patients: A Prospective Study
ConclusionsRiociguat treatment was associated with increased RVSVI and trends for improvement in myocardial remodeling in CTEPH patients. A larger clinical study is warranted to observe the therapeutic benefits of riociguat on RV remodeling.

Effect of Antihypertensive Medication on Cerebral Small Vessel Disease Brief Report
Conclusions—AHM has a protective effect on the progression of white matter hyperintensities, but no effect on brain atrophy. There are no trials on the effect of AHM on lacunes, microbleeds, enlarged perivascular spaces, or acute small subcortical infarcts.

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.

Characteristics of Ventricular Function in Pulmonary Hypertension Patients 
with Different Shape of Interventricular Septum:
Preliminary Study with Cardiac Magnetic Resonance Imaging
Background and objective To study the characteristics of ventricular function in Pulmonary Hypertension (PH) Patients with different shape of Interventricular Septum (IVS) by cardiac magnetic resonance (CMR). Methods 36 PH patients diagnosed by right heart catheterization accepted CMR. According to the morphology of IVS, the patients were divided into two groups: the non-deformation group (10 patients) and the deformation group (26 patients). The ventricular function parameters were as follows: RV and LV end-diastolic volume index (EDVI), end-systolic volume index (ESVI), stroke volume index (SVI), cardiac index (CI), ejec...

Workup and Management of Patients With Paradoxical Low-Flow, Low-Gradient Aortic Stenosis
AbstractAbout 60% of patients with paradoxical low-flow, low-gradient (PLF-LG) aortic stenosis (AS) have a severe disease that justifies aortic valve replacement (AVR). The first step in patients with symptomatic PLF AS should be to rule out measurement errors and treat hypertension. The second step is to distinguish pseudo-severe from true severe AS (TSAS). The third step is to select the optimal treatment modality at the right time. Regarding the second step, projected aortic valve area calculated using stress echocardiography is superior to traditional severity criteria (AVA<  1.0 cm2 and mean gradient ≥ 40 m...

Hypovolemia due to cerebral salt wasting may contribute to stroke in tuberculous meningitis
ConclusionIn TBM, stroke occurred in 39.5% of the patients, 50% of whom had CSW. Volume contraction due to CSW may contribute to stroke.

Reproducibility of peak filling and peak emptying rate determined by cardiovascular magnetic resonance imaging for assessment of biventricular systolic and diastolic dysfunction in patients with pulmonary arterial hypertension
AbstractRight ventricular (RV) and left ventricular (LV) diastolic stiffness may be independent contributors to disease progression in pulmonary arterial hypertension (PAH). The aims of this study are to assess reproducibility of peak emptying rate (PER) and early diastolic peak filling rate (PFR) for both the RV and the LV in PAH and study their relationship to stroke volume (SV). Triple weekly repetition of 20 (totalling 60) cardiovascular magnetic resonance (CMR) scans, were done on 10 patients with PAH and 10 healthy controls. RV and LV volumes were measured over the full cardiac cycle. PER and PFR were calculated as t...

Plasma A{beta} (Amyloid-{beta}) Levels and Severity and Progression of Small Vessel Disease Clinical Sciences
Background and Purpose—Cerebral small vessel disease (SVD) is a frequent pathology in aging and contributor to the development of dementia. Plasma Aβ (amyloid β) levels may be useful as early biomarker, but the role of plasma Aβ in SVD remains to be elucidated. We investigated the association of plasma Aβ levels with severity and progression of SVD markers.Methods—We studied 487 participants from the RUN DMC study (Radboud University Nijmegen Diffusion Tensor and Magnetic Resonance Imaging Cohort) of whom 258 participants underwent 3 MRI assessments during 9 years. We determined baseline plasma Aβ38, Aβ40, and AÎ...

Age-Specific Associations of Renal Impairment With Magnetic Resonance Imaging Markers of Cerebral Small Vessel Disease in Transient Ischemic Attack and Stroke Clinical Sciences
Background and Purpose—It has been hypothesized that cerebral small vessel disease (SVD) and chronic renal impairment may be part of a multisystem small-vessel disorder, but their association may simply be as a result of shared risk factors (eg, hypertension) rather than to a systemic susceptibility to premature SVD. However, most previous studies were hospital based, most had inadequate adjustment for hypertension, many were confined to patients with lacunar stroke, and none stratified by age.Methods—In a population-based study of transient ischemic attack and ischemic stroke (OXVASC [Oxford Vascular Study]), we evalu...

Left ventricular hypertrophy diagnosed after a stroke: a case report
ConclusionsElectrocardiogram diagnosis of left ventricular hypertrophy led to the diagnosis of apical hypertrophic cardiomyopathy in this patient. Left ventricular hypertrophy was only evident a few days after our patient suffered a stroke. The underlying mechanisms responsible for this remain unclear. Furthermore, differential diagnosis of hypertrophic cardiomyopathy should be considered in people with electrocardiogram criteria for left ventricular hypertrophy. Cardiovascular magnetic resonance imaging is an important diagnostic tool in identifying causes of left ventricular hypertrophy. Family screening should be recomm...
