Echocardiography in assessing acute pulmonary hypertension due to pulmonary embolism.
1980
Eighteen patients with acute pulmonary embolism were studied with right heart catheterization and M mode echocardiography. No patient had evidence of preexisting cardiopulmonary disease; pulmonary embolism was documented with pulmonary angiography. The mean pulmonary arterial pressure correlated with the angiographic severity index of embolic obstruction (r = 0.61, p 2 , p 2 ) and in 5 patients with acute pulmonary embolism and a mean normal pulmonary arterial pressure (10.9 ± 0.4 mm/m 2 ). For all measurements the index size of the right pulmonary artery correlated with the mean pulmonary arterial pressure (r = 0.84, p
Magnesium metabolism in hypertension and type 2 diabetes mellitus.
2007
The increasing evidence for the clinical relevance of altered magnesium metabolism to states of altered insulin resistance confirms the role of magnesium deficit as a possible underlying common mechanism of the "insulin resistance" of hypertension and altered glucose tolerance. The pioneer work of Lawrence M. Resnick and his group using the cellular ion-based approach that we are only partially presenting here has consistently contributed to the progress of the field, demonstrating (a) the critical importance of magnesium metabolism in regulating insulin sensitivity as well as vascular tone, and blood-pressure homeostasis; (b) that magnesium deficiency, defined on the basis of intracellular…
The effect of exercise training on blood pressure in menopause and postmenopausal women: A systematic review of randomized controlled trials
2021
The prevalence of hypertension is higher in postmenopausal than in premenopausal women. Regular exercise training has been shown to be effective in addressing hypertension. The aim of this systematic review was to synthesize the effect of exercise training on systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) in menopausal and postmenopausal women. This review was reported according to the PRISMA statement and registered in PROSPERO. The literature search was done in MEDLINE, Embase, Cochrane CENTRAL and ClinicalTrials. Randomized controlled trials involving menopausal and postmenopausal women undergoing exercise training were included. Two blinde…
The Ionic Hypothesis of Aging
1998
The clinical association of essential hypertension with metabolic abnormalities, such as hyperinsulinemia, insulin resistance, obesity, altered glucose tolerance and/or frank non-insulin dependent diabetes mellitus (NIDDM) has long been appreciated(1). Each of the above clinical conditions is extremely frequent in the elderly. The association of these different clinical states, that is also common at younger ages, has been termed “Syndrome X” and more recently “Generalized Cardiovascular-Metabolic Disease.”(2,3) Although several hypothesis have been proposed, including a primary role of hyperinsulinemia and insulin resistance, the mechanism(s) of this linkage has not been established. This …
In vivo antihypertensive mechanism of lactoferrin-derived peptides: Reversion of angiotensin I- and angiotensin II-induced hypertension in Wistar rats
2015
Novel peptides with antihypertensive effects in SHR rats have previously been identified in lactoferrin (LF) hydrolysates. To investigate their in vivo antihypertensive mechanism, we have assessed the blood pressure lowering effects of two of these LF-derived peptides (RPYL and DPYKLRP) in Wistar rats subjected to either angiotensin I- or angiotensin II-induced hypertension. Blood pressure was measured by the tail-cuff method, hypertension was induced by subcutaneous infusion of angiotensins, and then captopril, valsartan or LF-derived peptides orally administered. Angiotensin I- and angiotensin II-induced hypertension were reversed by captopril and valsartan, respectively. RPYL and DPYKLRP…
Mediterranean diet and antihypertensive drug use: a randomized controlled trial
2021
Objective To examine in older individuals at high cardiovascular risk whether following a Mediterranean diet decreased the necessity of antihypertensive drugs and modulated their associated cardiovascular risk. Methods In the PREvencion con DIeta MEDiterranea study, we assessed whether volunteers randomly allocated to an intervention with a Mediterranean diet enriched with extra-virgin olive oil or nuts (relative to a low-fat control diet) disclosed differences in the risk of: initiating antihypertensive medication in nonusers at baseline (n = 2188); and escalating therapy in participants using one, two, or three drugs at baseline (n = 2361, n = 1579, and n = 554, respectively). We also ass…
The impact of occult renal failure on the cardiovascular risk stratification in an elderly population: the PREV-ICTUS study.
2008
To analyze the impact of occult renal failure (ORF) in the individual risk stratification and on the blood pressures (BP) and low-density lipoprotein (LDL) goals in an aged population, according to the ESH/ESC Hypertension Guidelines.A cross-sectional, population-based study on individuals aged 60 years or more carried out in Primary Care Centers of Spain. Kidney function was estimated from calculated creatinine clearance (eGFR), Cockroft and Gault formula. Ten-year cardiovascular risk was estimated through the ESH/ESC table including or not including the eGFR. Estimates of the modification in BP and LDL-cholesterol (cLDL) goals were calculated.In 6419 subjects, 4242 subjects (66%) had norm…
Vacuum-Assisted Abdominal Closure in Surgical Emergency: A Single Institution Experience Treating a Cohort with a Prevalence of Faecal Peritonitis
2021
Abstract Vacuum-assisted abdominal closure (VAAC) has evolved as a promising method for treatment of emergent surgical patients. The aim of the study was an assessment of the complication rate and outcomes following routine application of VAAC in a cohort of patients suffering predominantly with peritonitis of the lower gastrointestinal tract (GIT) origin. The prospectively collected data was analysed retrospectively, including demographic data, aetiological factors, comorbid conditions and severity of the disease. The indications for VAAC included complicated intra-abdominal infection, purulent peritonitis with sepsis and/or risk of increased intra-abdominal pressure. In total, 130 patient…
