The Role of Ambulatory Blood Pressure Monitoring in Diagnosis of Hypertension and Evaluation of Target Organ Damage

2010

The goal of blood pressure (BP) measurement in children and adolescents is to provide strategies for promoting cardiovascular health which should be integrated into a comprehensive pediatric health-care program. Blood pressure, however, is a parameter that changes on a beat-to-beat basis in response to a variety of physiological and environmental stimuli. Nevertheless, casual BP measurement has provided the basis for present knowledge of the potential risk associated with hypertension (1) and has guided patient management for many years (2). A few BP measurements obtained in the office, on the contrary, may not necessarily reflect the true BP of an individual. Subsequently, a better charact…

P124 The impact of the new American college of cardiology/american heart association (ACC/AHA) definition of hypertension on atherosclerotic vascular…

2020

Background The 2017 ACC/AHA guidelines define hypertension as ≥130/80 mmHg instead of ≥140/90 mmHg. Studies in systemic autoimmune diseases, where blood pressure (BP) is fluctuating over time, were not considered. Our aim was to assess the impact of the new definition on the prevalence and incidence of atherosclerotic vascular events (AVEs) in systemic lupus erythematosus (SLE). Patients-Methods SLE patients with at least two years of follow-up and no previous AVEs were divided in three groups (≥140/90 mmHg, 130–139/80–89 mmHg and Results 1532 patients satisfied the inclusion criteria (88.1% females, mean age at baseline 36.2±14.3 years, mean disease duration 6.1±6.3 years). The prevalence …

Cardiovascular primary prevention risk factors in a nationwide survey, ABC (atrial fibrillation, high blood pressure and high cholesterol) risk facto…

2021

Abstract Background The National Health Service in England “Long Term Plan” aims to prevent 150,000 strokes and myocardial infarctions over the next 10 years. To achieve this, resources are being allocated to improve early detection of conditions strongly associated with cardiovascular disease. This includes working towards people routinely knowing their “ABC” risk factors (“A”: atrial fibrillation (AF), “B': hypertension and “C”: high cholesterol) (1). Purpose The aims of this study were to: 1) determine the proportion of participants with “A”, “B”, and “C” criteria; and 2) to identify risk factors for patients fulfilling any of these criteria. Methods LIPIDOGRAM2015 was a nationwide cross…

Acute and Chronic Captopril, but Not Prazosin or Nifedipine, Normalize Alterations in Adrenergic Intracellular Ca2+ Handling Observed in the Mesenter…

2004

The effect of hypertension and acute (36-h) or chronic (from age 6 to 16 weeks) antihypertensive treatment with prazosin (2 mg kg(-1) per day), nifedipine (50 mg kg(-1) per day), or captopril (50 mg kg(-1) per day) on Ca2+ mobilization due to alpha1-adrenoceptor activation was analyzed in functional studies using arterial rings [four conductance/distributing vessels: aorta, main mesenteric, iliac, and tail arteries and two resistance vessels; first and second small mesenteric artery branches obtained from spontaneously hypertensive rats (SHR, 6 and 16 weeks old) and age-matched Wistar Kyoto rats (WKY)]. Maximal response to noradrenaline in the presence of extracellular Ca2+ is not affected …

A mathematical model of cardiovascular dynamics for the diagnosis and prognosis of hemorrhagic shock

2020

Abstract A variety of mathematical models of the cardiovascular system have been suggested over several years in order to describe the time-course of a series of physiological variables (i.e. heart rate, cardiac output, arterial pressure) relevant for the compensation mechanisms to perturbations, such as severe haemorrhage. The current study provides a simple but realistic mathematical description of cardiovascular dynamics that may be useful in the assessment and prognosis of hemorrhagic shock. The present work proposes a first version of a differential-algebraic equations model, the model dynamical ODE model for haemorrhage (dODEg). The model consists of 10 differential and 14 algebraic e…

The influence of dopamine on hemodynamics, microcirculation and renal function in patients with hypnotic drug intoxication

1976

The effect of dopamine on hemodynamics (CO, AoPm, TPR, SV, SW, CVP, PAPm, PAEDP), microcirculation (MBF, PS-product) and renal function (VU, CKI, CNa, CK, Cosm, TcH2O) was studied in 8 patients with hypnotic drug poisoning. With increasing doses of dopamine, cardiac output and heart rate increased and the peripheral resistance decreased. An augmentation of stroke volume and left ventricular stroke work was observed in the low dose range only (200--400 mug/min). With increasing doses, central venous pressure as well as mean pulmonary artery pressure and enddiastolic pulmonary artery pressure decreased. No vasoconstriction was found in muscle tissue vessels even with large doses of dopamine. …
