68 patients with stroke treated at Hue Central Hospital from March to June 2004. Risk factors as hypertension, smoking were evaluated. Patients had clinical and paraclinical examination such as CT scanning of cerebral skull, blood formula. Blood level of homocystein was estimated: The prevalence of stroke in gender male/female was 1.64/1 with 61.76% men and 38.24 women. Hypertension 85.24%, men/women 1.64/1. Smoke 67.65%. Blood level of homocystein increases in stroke by the rate of 77.94%, as for hemorrhagic stroke was 65.63%, for ischemic stroke was 88.57%. Stroke rate increased by age, especially after 55 years old. A positive correlation between blood level of homocystein and hematocrite was notified

A prospective study including 70 patients with acute cerebral infarction at Hospital 108 from July 2004 to Jun 2005. Results: Increasing blood glucose level is very common among acute stroke patients accounting for 54.3%. Blood glucose level due to response during acute stroke is commonly within the range of 7 – 10mmol/l (50%). There are reverse correlations between blood glucose and Glasgow, Herry and Barthel scores. HbA1c is essential to differentiate hyperglycemia due to diabetes or response

The concentration of blood homocystein (Hcy) in 26 patients with cerebrovascular accident (CVA) was determined preliminarily in Central Hospital in Hue city. 57.69% was the incidence of CVA in male and 42.31% in female patients (in male it was 1.36 fold higher than in female). Hcy concentration increased in 80.77% CVA patient. The rate of increase of blood level of Hcy was 66.67% in brain hemorrhage, 92.86% in brain infarctus. The incidence of CVA enhanced with the age, especially after the age of 55. High blood pressure accounted for 76.92% in CVA. 17/26 (65.38%) was the ratio of tobacco smoler.

Hypertension is the most important risk factor for stroke. Blood pressure control results in significant reduction in most cardiovascular events, especially stroke. Several recent studies investigated the effects of tight blood pressure control on the development of cardiovascular events including stroke. On the other hand, besides mean blood pressure, which is the conventional target for hypertension management, the importance of blood pressure variability has been issued recently. Optimal target of blood pressure level and blood pressure variability for stroke prevention will be discussed.

OBJECTIVEThe same person's pulmonary venous blood volume, left atrial volume and stroke volume were measured by lung CT scans and cardiac CT angiography (CTA). Then their relationships were analyzed in order to investigate the mechanism of breathing control.

METHODSAs we described before, full pulmonary vascular (-0.6mm) volume was accurately calculated by three-dimensional imaging technology from lung CT scan; left atrial volume and stroke volume of left ventricle were calculated from the CTA data. Then the relationships among them were analyzed for estimation of the lung-artery time.

RESULTSThe total volume of lung and pulmonary vascular blood was 3486 ± 783 (2156-4418) ml, and the pulmonary vascular blood volume was 141 ± 20 (105-163) ml. The estimated pulmonary venous volume was 71 ± 10 (52-81) ml. Left atrial volume at the end diastolic was 97 ± 39 (53-165) ml, Stroke volume of left ventricle was 86 ± 16 (60-106) ml. Pulmonary venous volume and the left atrial volume were double of stroke volume(1.7-2.4).

CONCLUSIONThe estimated lung-artery time was three heart beat.

Despite declines in morbidity and mortality in recent years, ischemic stroke (IS) remains one of the leading causes of death and disability from cerebrovascular diseases. Addressing the controllable risk factors underpins the successful clinical management of IS. Hypertension is one of the most common treatable risk factors for IS and is associated with poor outcomes. Ambulatory blood pressure monitoring has revealed that patients with hypertension have a higher incidence of blood pressure variability (BPV) than those without hypertension. Meanwhile, increased BPV has been identified as a risk factor for IS. The risk of IS is higher and the prognosis after infarction is worse with higher BPV, no matter in the acute or subacute phase. BPV is multifactorial, with alterations reflecting individual physiological and pathological changes. This article reviews the current research advances in the relationship between BPV and IS, with an attempt to raise awareness of BPV among clinicians and IS patients, explore the increased BPV as a controllable risk factor for IS, and encourage hypertensive patients to control not only average blood pressure but also BPV and implement personalized blood pressure management.
