White-coat hypertension and cardiovascular risk
1995
OBJECTIVE: To compare cardiovascular risk in white-coat hypertensives, normotensives and established hypertensives. METHODS: We studied 61 hypertensive individuals, 27 of whom were white-coat hypertensives, and 35 normotensives. All subjects underwent 24 h noninvasive blood pressure monitoring and Doppler echocardiographic examination of the heart; urine was tested for microalbuminuria and the fundi of the eyes examined for retinopathy. RESULTS: The 24 h as well as the day- and night-time mean systolic blood pressure (SBP) was slightly but significantly higher in white-coat hypertensives than in normotensives; no significant difference was observed in diastolic blood pressure (DBP) between …
A multiple biomarker risk score for guiding clinical decisions using a decision curve approach.
2011
Aims: We assessed whether a cardiovascular risk model based on classic risk factors (e.g. cholesterol, blood pressure) could refine disease prediction if it included novel biomarkers (C-reactive protein, N-terminal pro-B-type natriuretic peptide, troponin I) using a decision curve approach which can incorporate clinical consequences. Methods and results: We evaluated whether a model including biomarkers and classic risk factors could improve prediction of 10 year risk of cardiovascular disease (CVD; chronic heart disease and ischaemic stroke) against a classic risk factor model using a decision curve approach in two prospective MORGAM cohorts. This included 7739 men and women with 457 CVD …
The effects of telmisartan alone or in combination with hydrochlorothiazide on morning home blood pressure control: The SURGE 2 practice-based study
2013
SURGE 2, a large-scale, practice-based study in 10 countries, evaluated the effects of telmisartan alone or with hydrochlorothiazide (HCTZ) on morning (06:00 – 11:59) home blood pressure (HBP) control. Hypertensive patients (clinic blood pressure [BP] 140/90 mmHg) received telmisartan 40 or 80 mg either alone or in combination with HCTZ 12.5 mg for 8 weeks. Treatment could be adjusted if clinic BP remained 140/90 mmHg. Clinic BP was measured in the morning prior to medication, and seated HBP monitoring was performed, three times per day, 2 days per week. A total of 25,882 patients were included (71% were previously using antihypertensives). There was a statistically signifi cant (all p 0.00…
Effects of drug therapy on cardiac arrhythmias and ischemia in hypertensives with LVH.
2001
Left ventricular hypertrophy (LVH) in hypertensive subjects is associated with an increased prevalence of ventricular arrhythmias. To evaluate the effect of antihypertensive treatment on cardiac arrhythmias (CA) and transient episodes of myocardial ischemia (TEMI), we studied 46 hypertensive patients with LVH, divided into four groups randomly treated with enalapril, hydrochlorothiazide (HCTZ), atenolol, or verapamil (SR-V) for 6 months. Office blood pressure and office heart rate values were recorded, in basal conditions, after 1 and 6 months of treatment, and all patients underwent echocardiography, electrocardiographic Holter monitoring, and stress testing. All drugs significantly lowere…
Systemic vascular resistance predicts the development of hypertension: the cardiovascular risk in young Finns study
2020
To study whether systemic hemodynamics, especially systemic vascular resistance, predicts the development of hypertension and improves the risk prediction of incident hypertension beyond common risk factors in the risk models in young adults.Typical risk factors for hypertension in the risk prediction models (systolic and diastolic blood pressure, parental history of hypertension, age, sex, body-mass index, smoking), laboratory values (high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, glucose, insulin, C-reactive protein), heart rate (HR), stroke index (SI), and systemic vascular resistance index (SVRI) calculated by whole-body impedance cardiography …
Psychophysiological responses to the Stroop Task after a maximal cycle ergometry in elite sportsmen and physically active subjects.
2001
Physical fitness moderates the psychophysiological responses to stress. This study attempts to determine whether the degree of fitness could affect the response to physical and psychological stress after comparing two groups of men with good physical fitness. Saliva samples from 18 elite sportsmen, and 11 physically active subjects were collected to determine hormonal levels after carrying out a maximal cycle ergometry. Heart rate and skin conductance level were continuously recorded before, during, and after a modified version of the Stroop Color-Word Task. With similar scores in trait anxiety and mood, elite sportsmen had lower basal salivary testosterone, testosterone/cortisol ratio, and…
Age, homocysteine, and oxidative stress: Relation to hypertension and type 2 diabetes mellitus
2010
Abstract OBJECTIVES: Hyperhomocysteinemia and oxidative stress are independent risk factors for cardiovascular events, which occur more frequently in old age. We evaluated these parameters in relation to age and the presence of hypertension and type 2 diabetes mellitus. METHODS: Two hundred eighty-two subjects (female/male: 142/140; 141 were >65 years and 141 were <65 years; mean age 73.9 +/- 6.6 years and 52.5 +/- 8.2 years, respectively) were randomly recruited from those attending our institution. Blood pressure, anthropometric parameters, oxidative stress parameters (reactive oxygen species [ROS] and malondialdehyde [MDA]), and homocysteine levels were evaluated in participants. RESULTS…
Detection of central pulmonary artery thromboemboli by transesophageal echocardiography in patients with severe pulmonary embolism.
1992
Transthoracic echocardiography generally provides only indirect signs of pulmonary embolism. In contrast, with transesophageal echocardiography the thromboembolus itself can be visualized in the central parts of the pulmonary artery. The aims of our study were to evaluate, first, the incidence of central pulmonary artery thromboemboli in patients with severe pulmonary embolism, and second, the accuracy of the echocardiographic diagnosis. Our study group comprised 60 patients with proved severe pulmonary embolism. All patients were examined by transthoracic and transesophageal echocardiography. The echocardiographic findings concerning the absence or presence of central pulmonary artery thro…
Sympathetic Activity and Blood Pressure Pattern in Autosomal Dominant Polycystic Kidney Disease Hypertensives
1998
To study the potential role of sympathetic activity in the pathogenesis of arterial hypertension associated with autosomal dominant polycystic kidney disease (ADPKD) and to analyze its relationship with 24-hour blood pressure pattern, plasma catecholamines and 24-hour ambulatory blood pressure monitoring were evaluated in 30 ADPKD hypertensive patients (of which 17 without and 13 with renal failure) and in 50 essential hypertensives. The groups were matched for sex, body mass index, known duration of hypertension, and clinic blood pressure. Plasma catecholamines, determined in resting position, were higher in ADPKD patients without renal failure than in essential hypertensives. Nighttime di…
Increased expression of markers of early atherosclerosis in patients with inflammatory bowel disease.
2016
Recent studies documented an increased cardiovascular risk in patients with inflammatory bowel disease (IBD). Our study aimed at investigating the prevalence of intima-media thickness (IMT) of the carotid arteries and the arterial stiffness indices as markers of early atherosclerosis in young IBD patients.We recruited 68 consecutive IBD patients, and 38 matched healthy controls less than 45years old (median age 31.6±8.1years). Clinical and demographic features, cardiovascular risk factors, history of cardiovascular events, concomitant therapies were registered on a dedicate database. Carotid IMT was evaluated by using high resolution B-mode ultrasonography. Arterial stiffness was assessed b…
