STEMI vs NSTEACS management trends in non-invasive hospital.
CONCLUSION: NSTEACS patients in western province of KSA present at an older age are mostly males and have higher prevalence of hypertension and hyperlipidemia compared with STEMI patients. It is therefore important to identify patients with high-risk profile and put implement measures to reduce these factors. PMID: 27543475 [PubMed - in process]

A Zero-Dimensional Model and Protocol for Simulating Patient-Specific Pulmonary Hemodynamics From Limited Clinical Data
The objective of this study was to develop and validate a 0D computational model, along with a numerical implementation protocol, of the RV –PA axis. Model results are qualitatively compared with published clinical data and quantitatively validated against right heart catheterization (RHC) for 115 pediatric PH patients. The RV–PA circuit is represented using a general elastance function for the RV and a three-element Windkessel init ial value problem for the PA. The circuit mathematically sits between two reservoirs of constant pressure, which represent the right and left atriums. We compared Pmax, Pmin, mPAP, cardiac ...

MRI derived left atrial volume index predicts treatment response in patients with PAH
Conclusion: This study shows that in patients meeting the haemodynamic criteria for PAH, patients with an elevated LA volume had poor response to PAH therapy. Further work to better characterize this PAH phenotype and recognize the importance of comorbidities in predicting response to therapy is required.

Age is independently associated with pulmonary arterial compliance in health and in patients with pulmonary vascular disease
Discussion: Advancing age is independently associated with pulmonary arterial compliance in health and disease. In contrast to younger patients, pulmonary arterial compliance does not increase in response to PAH therapy in older patients.

Left ventricular deformation at rest predicts exercise ‐induced elevation in pulmonary artery wedge pressure in patients with unexplained dyspnoea
ConclusionLeft ventricular deformation at rest predicts exercise‐induced rise in PAWP among patients with dyspnoea and a preserved LVEF. A pattern of rest deformation characterized by worse LS and exaggerated CS is most strongly associated with exercise‐induced rise in PAWP.

Contrast ‐induced encephalopathy following cardiac catheterization
ConclusionsCIE is an important clinical entity to consider in the differential diagnosis of stroke following cardiac catheterization. Given that prognosis is excellent with supportive management only, physicians should be aware of it, and consider it prior to initiating thrombolysis. © 2016 Wiley Periodicals, Inc.

Recurrent contrast ‐induced encephalopathy following coronary angiography
Contrast‐induced encephalopathy (CIE) is an acute and reversible neurological disturbance associated with the intra‐arterial administration of iodinated contrast medium during cardiac catheterisation. It may manifest with encephalopathy, motor and sensory disturbances; vision disturbances, including cortical blindness, ophthalmoplegia, aphasia; and seizures. Disruption of the blood–brain barrier and direct neuronal toxicity are believed to be implicated in the pathophysiology of the syndrome. Symptoms appear soon after contrast administration and resolve completely within 24–48 h. Risk factors may include hypertens...

Comorbidities and Complications in Nonagenarians Undergoing Coronary Angiography and Intervention.
Authors: Gayed M, Yadak N, Qamhia W, Daralammouri Y, Ohlow MA Abstract Elderly people represent the fastest growing portion of cardiovascular patients. We aimed to analyze the clinical presentation, risk factors, co-morbidities, complications, and mortality in patients 90 years or more who underwent coronary angiography and intervention.We retrospectively studied 108 (0.25% of 43,385) consecutive patients ≥ 90 years undergoing cardiac catheterization and/or intervention in a tertiary specialist hospital between 2003 and 2014.Most patients (68.5%) were introduced on an emergency basis, especially with acute corona...

RVOT-VTI/PASP Is a Novel Noninvasive Parameter of Pulmonary Artery Compliance and Improves After Treatment with Pulmonary Hypertension-Specific Therapy
Pulmonary artery compliance (PAC) is an independent predictor of mortality in patients with pulmonary hypertension (PH). We have previously shown that the ratio of echocardiography derived right ventricular outflow tract velocity time integral (RVOT-VTI; an estimate of stroke volume) to pulmonary artery systolic pressure (PASP) correlates with PAC measured by right heart catheterization. We sought to determine whether PH-specific therapy improves PAC in patients with pulmonary arterial hypertension (PAH).

Clinical Significance of Pulmonary Arterial Capacitance Calculated by Echocardiography in Patients With Advanced Heart Failure.
CONCLUSIONS: Decreased PAC as measured by echocardiography, indicating elevated PAWP and RV dysfunction, predicted poorer outcomes in patients with advanced HF. PMID: 28679970 [PubMed - as supplied by publisher]

Right Ventricular Function Is Strongly Correlated With a Right Heart-Pulmonary System Rather Than With Right Ventricular Contractility
Background: RV function is a major determinant of clinical presentation in pulmonary hypertension. However, both of RVEF (MRI) and RVFAC (echocardiography) are highly load-dependent, and do not reflect RV contractility. Purpose: The aim of this study is to investigate the physiological correlates between RVFAC, RV contractility, RV afterload, and RV-PA coupling. Methods: Consecutive patients with PH who underwent RV catheterization and routine echocardiography were enrolled. RV afterload is estimated by arterial elastance (Ea), a ratio of end-systolic pressure to stroke volume.

The Prognostic Value of Follow-up Hemodynamic Variables After Initial Management in Pulmonary Arterial Hypertension.
Conclusions -SVI and RAP were the hemodynamic variables independently associated with death or lung transplantation at first follow-up RHC after initial PAH treatment. These findings suggest that the SVI could be a more appropriate treatment target than the cardiac index in PAH. PMID: 29070502 [PubMed - as supplied by publisher]

Transjugular intrahepatic portosystemic shunt: impact on systemic haemodynamics and renal and cardiac function in patients with cirrhosis.
CONCLUSIONS: TIPS increases CBV by increasing CO and SV, whereas HR is initially unaltered. These results indicate an inability to increase the heart rate in response to a hemodynamic challenge that only partially increases CBV after TIPS. These changes, however, are sufficient for improving renal function. PMID: 29074483 [PubMed - as supplied by publisher]

Left ventricular end-diastolic dimension and septal e ′ are predictors of cardiac index at rest, while tricuspid annular plane systolic excursion is a predictor of peak oxygen uptake in patients with pulmonary hypertension
AbstractLittle is known regarding a correlation of hemodynamics at rest or exercise capacity with echocardiographic parameters in patients with pulmonary hypertension (PH). To clarify these potential correlations, we performed transthoracic echocardiography, right heart catheterization, and cardiopulmonary exercise testing in 53 patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). Left ventricular end-diastolic dimension (LVDd), early diastolic velocity of the septal mitral annulus (septal e ′), tricuspid regurgitation peak gradient (TRPG), and tricuspid annular p...
