1. What is the meaning of a slow rate of rise of the carotid arterial pulse? A carotid arterial pulse that is reduced (parvus) and delayed (tardus) argues for aortic valvular stenosis. Occasionally this also may be accompanied by a palpable thrill. If ventricular function is good, a slower upstroke correlates with a higher transvalvular gradient. In left ventricular failure, however, parvus and...

A 68-year-old woman with long-standing severe pulmonary arterial hypertension was referred for coronary catheterization for investigation of worsening exertional dyspnea associated with angina. Coronary angiography revealed critical ostial left main coronary artery (LMCA) stenosis. Given the history of severe pulmonary arterial hypertension, simultaneous angiography of the LMCA and main pulmona...

Intracranial arterial disease includes thromboembolic events, vascular stenoses, and aneurysms. Endovascular techniques have been investigated for treatment of intracranial arterial disease, as an alternative to intravenous tissue plasminogen activator and supportive care for acute stenosis and as an alternative to risk factor modification for chronic stenosis. For cerebral aneurysms, stentassi...

BACKGROUND AND PURPOSE In the discussion on the cost-effectiveness of screening, precise estimates of severe asymptomatic carotid stenosis are vital. Accordingly, we assessed the prevalence of moderate and severe asymptomatic carotid stenosis by age and sex using pooled cohort data. METHODS We performed an individual participant data meta-analysis (23 706 participants) of 4 population-based s...

Takayasu disease is a chronic vasculitis of the large vessels. It rare in sub- Saharan Africa and probably under-diagnosed. Arterial hypertension (AH) frequent finding. We report case 46-year-old man with revealed by hypertension. The American College Rheumatology (ACR) criteria were used for diagnosis, 4 out 6 criteria. Echodoppler angioscanner showed signs left subclavian stenosis circumferen...

OBJECTIVE To describe a patient with a predominantly unilateral intracranial arterial stenosis who then developed metastatic lung cancer to the brain, with the tumors preferentially depositing in the underperfused cerebral hemisphere. DESIGN Case report. SETTING Inpatient neurology ward at a university medical center. Patient A 68-year-old woman with intracerebral arterial stenosis who then...

N 1962, we 1 published a report on the value of the comparative Usodium/Ucreatinine ratio in the diagnosis of hypertension due to renal arterial stenosis. This ratio is defined as the proportional relation between the concentration of sodium and creatinine (U5Odiu./Ucreatinine) in the urine issuing simultaneously from each ureter. We also suggested that routine performance of dehydrated-hydrate...

The flow of blood in narrow arteries with bell-shaped mild stenosis is investigated that treats blood as non-Newtonian fluid by using the K-L model. When skin friction and resistance of blood flow are normalized with respect to non-Newtonian blood in normal artery, the results present the effect of stenosis length. When skin friction and resistance of blood flow are normalized with respect to N...

conclusion peripheral arterial calcification is significantly correlated with cad extent in patients with pad. peripheral arterial calcification can be a useful marker for predicting multivessel-cad. results lecs in multivessel-cad were significantly higher than those in nonsignificant cad (10.0 ± 5.8 versus 4.0 ± 3.1, p < 0.001). lecs significantly correlated with ccs (r = 0.831, p < 0.001) an...

Among several factors determining secretion of renin is mean arterial pressure (Skinner, McCubbin, and Page, 1964). Plasma renin is, in some instances, increased in renal artery stenosis (Helmer, 1964; Brown et al., 1964; Veyrat et al., 1964): and it is probable that this increase is due to lowered arterial pressure beyond the obstruction. In coarctation of the aorta there is a similar discrepa...
