1.Coronary ischaemic disease and congestive heart failure are the principal causes of mortality in patients with peripheral vascular disease. Whether cardiac hypertrophy is present and even more pronounced in peripheral vascular disease than in other populations has never been explored. 2.Twenty-five hypertensive patients were investigated, 11 without and 14 with peripheral vascular disease, matched for age, sex, mean arterial pressure and antihypertensive drug treatment. Cardiac mass was determined using echocardiography together with measurement of systemic blood pressure, ratio between ankle systolic pressure (ASP) and brachial systolic pressure (BSP), and standard biochemical parameters including natriuresis per 24 ;h. 3.At the same mean arterial pressure, patients with peripheral vascular disease had a significantly higher cardiac mass (157±12 versus 116±6 ;g/m2; P< 0.01), pulse pressure (81±5 versus 55±4 ;mmHg; P< 0.01) and natriuresis (180±17 versus 144±6 ;mmol/24 h; P< 0.01) than controls. Using univariate correlations, cardiac mass was positively associated with pulse pressure, mean arterial pressure and natriuresis, and negatively with the ASP/BSP ratio. On the basis of multivariate regression analysis, only natriuresis was positively correlated to cardiac mass. 4.Patients with peripheral vascular disease develop a higher degree of cardiac hypertrophy in comparison with hypertensive subjects with the same level of mean arterial pressure. Sodium intake rather than mechanical factors seems to be the major modulating factor which influences the degree of cardiac hypertrophy.

Transcutaneous Oxygen Pressure

Spinal cord stimulation (SCS) may be helpful in treating pain and vascular insufficiency associated with inoperable peripheral vascular disease (PVD). Often decision-making regarding progression from trial to implantation is based on subjective measures. Transcutaneous oxygen pressure, a measure of microcirculation and tissue perfusion, provides information on changes that may occur in PVD patients that undergo SCS trials and may provide predictive information for patient outcomes. This article reports on 2 patients with severe PVD in which transcutaneous oxygen pressures were measured during the trial phase, guided progression to implantation, and were followed in the postoperative period. Transcutaneous oxygen pressure values continued to improve following permanent implantation. We provide a review on transcutaneous oxygen pressure monitoring, along with emphasis on the technical aspects of transcutaneous oxygen pressure monitoring and its incorporation into practice. The decision to implant a SCS should be based on not only subjective measures of improvement, but also objective measures of improvement in transcutaneous oxygen pressure. Additional research is warranted to develop transcutaneous oxygen pressure predictive indices to assist in the selection of patients for progression to permanent implantation. Key words: Spinal cord stimulation, peripheral vascular disease, transcutaneous oxygen pressure monitoring.

Introduction. 24-hour ambulatory blood pressure monitoring (ABPM) plays an important role in assessing cardiovascular prognosis, through presence or absence of ABPM-related prognostic features.Objectives. To study relationship between 24-hour ABPM and cardiovascular outcomes in patients from Chesterfield Royal Hospital.Material and Methods. Over 12 months from the 1st of August 2002, 1187 individuals had 24-hour ABPM performed. Cardiovascular outcomes were studied in a subset (297) of the original cohort, made up by every 4th consecutive subject. The following ABPM-related prognostic features were studied—high day time systolic and diastolic BP (≥135, ≥85 mmHg), high night time systolic and diastolic BP (≥120 mmHg, ≥75 mmHg), absence of nocturnal dip (≤10% fall in night time SBP), high early morning SBP (≥140 mmHg), and morning surge (≥20/15 mmHg). The cardiovascular outcomes studied in the fourth table included fatal and nonfatal MI, new diagnosis of angina, acute coronary syndrome, sudden cardiac death, cardiac arrhythmias, acute LVF, cerbrovascular events, peripheral vascular disease, abdominal aortic aneurysm, and CKD stage 3 or above.Results. Over a followup period of days (1720–2305 days) 82 cardiovascular events occurred in 61 subjects. Cardiac arrhythmias were the most common CV outcome (34 events) followed by cerebrovascular events (15). Statistically significant associations found were between cerebrovascular events and absent nocturnal dip ≤ 10% () and high day time DBP (), peripheral vascular disease and morning surge ≥ 20/15 mmHg (), cardiac arrhythmias and high day time and night time DBP ( and .033, resp.).Conclusion. Significant associations were found between cerebrovascular events and absent nocturnal dip ≤ 10% and high day time DBP, peripheral vascular disease and morning surge ≥ 20/15 mmHg, cardiac arrhythmias and high day time and night time DBP.

SummaryPlatelets tests, acute phase reactants and serum lipids were measured in patients with diabetes mellitus and patients with peripheral vascular disease. Patients frequently had abnormal platelet tests and significantly increased acute phase reactants and serum lipids, compared to young healthy control subjects. These differences were compared with multidiscriminant analysis. Patients could be separated in part from the control subjects with variables derived from the measurement of acute phase proteins and serum lipids. Platelet test results improved the separation between diabetics and control subjects, but not between patients with peripheral vascular disease and control subjects. Diabetic patients with severe retinopathy frequently had evidence of platelet activation. They also had increased acute phase reactants and serum lipids compared to diabetics with absent or nonproliferative retinopathy. In patients with peripheral vascular disease, only the fibrinogen concentration was related to the degree of vessel damage by arteriography.
