BACKGROUND: Morphological changes of the internal carotid arteries (McICA) are frequently found during cervical ultrasound studies. However, McICA's etiology remains controversial. During this study, the prevalence and demographic characteristics of McICA such as kinking, coiling or looping, identified by Doppler ultrasound, were analysed and its relationship with vascular risk factors and stroke was assessed. METHODS: A retrospective study was performed by analysing 19,804 patients between Jan 2000 and Jun 2012 who were submitted to cervical ultrasonographic study...

BACKGROUND AND AIMS: Pulmonary hypertension is common in patients with end-stage renal disease, and portends a poor prognosis. There are little data in this population, and previous studies have not evaluated quantitative changes in hemodynamics over time while on maintenance dialysis. This study sought to estimate changes in pulmonary artery systolic pressure (PASP) and right ventricular function over time, and to predict PASP change using clinical variables routinely available at time of initial measurement, in patients on maintenance dialysis...

Hypertension-stimulated cardiac hypertrophy and apoptosis play critical roles in the progression of heart failure. Our previous study suggested that hypertensive angiotensin II (Ang II) enhanced insulin-like growth factor receptor II (IGF-IIR) expression and cardiomyocyte apoptosis, which are involved JNK activation, sirtuin1 (SIRT1) degradation, and heat-shock transcription factor 1 (HSF1) acetylation. Moreover, previous studies have implied that short-term hypoxia (STH) might exert cardioprotective effects...

INTRODUCTION: Coronary microvascular dysfunction (MVD) may contribute to the pathogenesis of heart failure with preserved ejection fraction (HFpEF). Speckle-tracking echocardiography is a feasible and reproducible method for identifying abnormalities in left ventricular (LV) and left atrial (LA) function among HFpEF patients. By assessing myocardial flow reserve (MFR), positron emission tomography (PET) imaging enables quantitative assessment of coronary MVD. We hypothesized that, in patients with risk factors for HFpEF and normal epicardial perfusion on cardiac PET, abnormal MFR is associated with LV diastolic dysfunction (DD) and reduced LV and LA strain...

BACKGROUND: Among high-risk individuals, statins are beneficial for primary prevention of cardiovascular disease (CVD). In Nigeria, currently, there are no CVD prevention guidelines, so the use of CVD risk estimation to guide statin therapy is left to the discretion of the physician. OBJECTIVE: The objective of the study was to compare 3 CVD risk estimation tools in the evaluation of patients presenting to a tertiary hospital in Nigeria. METHODS: Cross-sectional study involving 295 patients with any CVD risk factors but not taking statins...

Diabetes, hyperlipidemia, and hypertension are modifiable risk factors that predict cardiovascular disease events. The effect of these risk factors on incident cardiovascular disease increases with progressively higher levels of glucose, low-density lipoprotein cholesterol, and blood pressure. The thresholds for initiating treatment of these modifiable risk factors and the optimal goals of risk factor modification are a focus of primary prevention research. Although an aggressive approach is appealing, adverse events may occur, and potential physiological barriers may exist...

Pulmonary hypertension (PH) is a deadly and increasingly prevalent vascular disease characterized by excessive pulmonary vascular remodeling and right ventricular dysfunction which leads to right heart failure, multiorgan dysfunction, and premature death. The cause of the vascular remodeling in PH remains elusive, and thus current treatments are marginally effective and prognosis of PH remains poor. Increasing evidence indicates the pathogenic importance of endothelial dysfunction in PH. However, the underlying mechanisms of such dysfunction are not well described...

Pulmonary hypertension is a devastating disease without cure. The major cause of death among patients with pulmonary hypertension is right heart failure; however, biology of the right heart is not well understood. This lack of knowledge interferes with developing effective therapeutic strategies to treat these patients. In this chapter, we summarize studies performed in our laboratory that investigated the role of redox signaling in the regulation of the right ventricle (RV), using rat models of experimental pulmonary hypertension and right heart failure...

Pulmonary hypertension is a complex disease of the pulmonary vasculature, which in severe cases terminates in right heart failure. Complex remodeling of pulmonary arteries comprises the central issue of its pathology. This includes extensive proliferation, apoptotic resistance and inflammation. As such, the molecular and cellular features of pulmonary hypertension resemble hallmark characteristics of cancer cell behavior. The vascular remodeling derives from significant metabolic changes in resident cells, which we describe in detail...

Normally, the pulmonary circulation is maintained in a low-pressure, low-resistance state with little resting tone. Pulmonary arteries are thin-walled and rely heavily on pulmonary arterial distension and recruitment for reducing pulmonary vascular resistance when cardiac output is elevated. Under pathophysiological conditions, however, active vasoconstriction and vascular remodeling lead to enhanced pulmonary vascular resistance and subsequent pulmonary hypertension (PH). Chronic hypoxia is a critical pathological factor associated with the development of PH resulting from airway obstruction (COPD, sleep apnea), diffusion impairment (interstitial lung disease), developmental lung abnormalities, or high altitude exposure (World Health Organization [WHO]; Group III)...

Pulmonary hypertension (PH) is a lung vascular disease with marked increases in pulmonary vascular resistance and pulmonary artery pressure (>25 mmHg at rest). In PH patients, increases in pulmonary vascular resistance lead to impaired cardiac output and reduced exercise tolerance. If untreated, PH progresses to right heart failure and premature lethality. The mechanisms that control the pathogenesis of PH are incompletely understood, but evidence from human and animal studies implicate nitrative stress in the development of PH...

The electrocardiogram (ECG) is a relatively insensitive tool for the detection of right ventricular hypertrophy (RVH), but some criteria have high specificity. The recommended ECG screening criteria for RVH are not sufficiently sensitive or specific for screening for mild RVH in adults without clinical cardiovascular disease. The greatest accuracy of the ECG is in congenital heart disease, with intermediate accuracy in acquired heart disease and primary pulmonary hypertension in adults.
