Filter by:Excess salt intake is a major contributor to high blood pressure, the leading individual risk factor for cardiovascular events, such as stroke, myocardial infarction and heart failure. According to PHYSA study, salt intake in Portugal remains much higher (10.7 g) than recommended by the international health organisations, indicating the need for effective implementation of salt reduction interventions. In Portugal the main source of daily salt intake is added salt during cooking, and salt content in bread, cheese and processed meat. The objective of this study is to determine the effectiveness of a dietary education program tailored for salt reduction. To assess the effectiveness of the salt reduction program the investigator's will measure changes in salt consumption levels, by evaluating the 24 h urinary sodium excretion. This study is a consortium-initiated, randomised, simple-blinded, controlled trial designed to assess the effectiveness of a salt reduction program versus generic healthy lifestyle program in the Lisbon Metropolitan Area.
The study includes two parts: 1) an observational study examines the association of meal frequency, meal timing, and meal regularity with short-term changes in blood pressure and body composition; 2) a randomized controlled intervention examines the influence of recommendation of increase breakfast frequency and decrease nighttime snacking on 1-year changes in blood pressure and body composition.
Right ventricular (RV) dysfunction in cardiac surgery is an independent risk factor for morbidity and mortality. Raising the systemic blood pressure with norepinephrine seems to have a positive influence on the right ventricular function in several animal studies. The current study is designed to evaluate the effect of a higher blood pressure on the RV function in post cardiac surgery patients.
This study aimed to evaluate the relationship between the perioperative blood pressure and postoperative mortality after cardiac surgery using performance measurement (PM) of mean arterial pressure (MAP).
This study will evaluate the effect of household-based screening and care encouragement for blood pressure on subsequent changes in blood pressure. The study uses a quasi-experimental regression discontinuity design with existing population-based secondary data from the 2008, 2010, 2012, 2014, and 2017 waves of the National Income Dynamics Study in South Africa.
This study compares the effect of individualized vs standard blood pressure management on postoperative myocardial injury in high-risk patients undergoing non-cardiac surgery by measuring the hs-cTnT levels. Continuous norepinephrine infusion is used to target a mean pressure of greater than 65mmHg and a systolic pressure less than 160mmHg in the standardized group while the target is 20% within the ward blood pressure in the individualized group. The pre- and postoperative hs-cTnT levels to detect myocardial injury are compared between the two groups.
The aim of this study was to investigate the effects of preoperative operating room environment introduction on preoperative hypertension and blood pressure in hypertensive patients.
Drainage manoeuvres described in different Manual Lymphatic Drainage methods, suggest modificactions in vital signs, by changes at nervous system, that would involve modifications to heart rate, breathing rate, blood pressure, cardiac vascular level (arteries and lymphatics). In addition this hypothetical relaxing effect could be beneficial for other types of pathologies associated with the presence of stress, cardiac problems, respiratory pathology, muscle tension, muscle trigger points, etc. With this study investigators compare different manoeuvres in the neck area to observe the results in the participants regarding the basal state.
The Nephrocare mHealth project supports patients with Chronic Kidney Disease with a mobile application and telemonitoring. The application includes the follow-up of blood pressure.
American College of Cardiology/American Heart Association (ACC/AHA) hypertension guidelines recommend lifestyle modification for patients with elevated blood pressure. While eating a Dietary Approaches to Stop Hypertension (DASH)-type diet, increasing physical activity, and weight loss have been shown to reduce blood pressure, limited resources are available in the primary care setting to help patients make these changes. In this study, the investigators will compare the efficacy of a self-guided vs. dietitian-led approach using web-based lifestyle modification tools to reduce weight, improve dietary quality, and lower blood pressure in overweight/obese adults with elevated blood pressure.
