Comportamento da circulação pulmonar e do ventriculo direito em pacientes portadores de hipertensão arterial sistemica não complicada estudo em repouso e no exercicio

Orientador : Eduardo Arantes NogueiraTese (doutorado) - Universidade Estadual de Campinas, Faculdade de Ciencias MedicasResumo: Foram estudados 29 pacientes portadores de hipertensão arterial sistêmica não complicada, sendo 17 do sexo feminino, com idade variando de 32 a 64 anos. Em todos os pacientes o diagnóstico de hipertensão arterial sistêmica foi feito após quatro semanas de observação, sem medicação. O estudo contou das medidas dos seguintes parâmetros hemodinâmicos: a)frequência cardíaca, (FC), pressão média do átrio direito (AD), pressão arterial pulmonar sistólica (PPS) pressão arterial pulmonar diastólica (PPD),pressão arterial pulmonar média(PPM), pressão média do capilar pulmonar (CP) pressão arterial sistólica da aorta (PSA)pressão arterial diastólica da aorta (PDA) pressão arterial média da aorta( PMA), índice cardíaco (IC), índice sistólico(IS), trabalho do ventrículo direito (TVD), trabalho do ventrículo esquerdo (TVE), resistência arteriolar pulmonar (RAP) resistência vascular sistêmica (RVS) em repouso e com exercício de 50 e 100 w/s. Os resultados foram os seguintes:1) Frequência Cardíaca (Grupo Geral) A FC (em bpm), variou de 79,5 ± 12,7 (54-107), em repouso, e 114,6 ± 14,8 (86-139) com 50w/s (p<0,05) e 150,6 ± 24,3 bpm (103-206) com 100w/s (p<0,05). CONTINUA.......RESUMO COM 10 PAGINASAbstract: Twenty nine patients with systemic arterial hypertension were studied. There was 17 females and 12 males whose ages ranged from 32 to 64 years. The diagnosis of systemic arterial hypertension was made after 4 weeks of observation without drugs. The following hemodynamic parameters were studied: a) heart rate (HR), mean right atrial pressure (RAP), systolic pulmonary artery pressure (SPP), diastolic pulmonary artery pressure (DPP), mean pulmonary artery pressure (MPP), mean pulmonary wedge pressure (WP), aortic systolic pressure (ASP), aortic diastolic pressure (ADP), aortic mean pressure (AMP), cardiac index (CI), systolic index (SI), right ventricular work (RVW) , left ventricular work (LVW), pulmonary arteriolar resistance (PAR) and systemic vascular resistance (SVR) at rest and during exercise with 50 and 100 w/s. The following results were found: 1) Heart Rate (Ali Patients) Heart rate changed from 79.5 + 12.7 b/m (54 -107) at rest to 114.6 + 14.8 b/m (86 - 136) during 50 w'/s exerci se and to 150.6 + 24.3 b/m (103 -206) during 100 w/s exerci se. 2) Heart Rate (Group A) Heart rate changed frem 74.1 + 12.6 b/m ( 54 - 107) at rest to 110 + 14.3 b/m (89 -139) during 50 w/s exercise and to 150 + 23.9 b/m (113 -193) during 100 w/s exercise (p<0.05)DoutoradoDoutor em Medicin

Prevalence and treatment of hypertension in urban and riverside areas in Porto Velho, the brazilian Amazon

Hypertension (HTN) is a preventable cause of cardiovascular morbidity and mortality. Objectives: To compare the prevalence, awareness, treatment, and control of HTN among urban and riverside populations in Porto Velho, Amazon region. Methods: We conducted a cross-sectional study between July and December 2013 based on a household survey of individuals aged 35–80 years. Interviews by using a standardized questionnaire, and blood pressure (BP), weight, height, and waist circumference measurements were performed. HTN was defined when individuals reported having the disease, received antihypertensive medications, or had a systolic BP ≥ 140 mm Hg or diastolic BP ≥ 90 mm Hg. Awareness was based on self-reports and the use of antihypertensive medications. Control was defined as a BP ≤ 140/90 mm Hg. Results: Among the 1410 participants, 750 (53.19%) had HTN and 473 (63.06%) had diagnosis awareness, of whom 404 (85.41%) received pharmacological treatment but with low control rate. The prevalence and treatment rates were higher in the urban areas (55.48% vs. 48.87% [p = 0.02] and 61.25% vs. 52.30% [p < 0.01], respectively). HTN awareness was higher in the riverside area (61.05% vs. 67.36% ; p < 0.01), but the control rates showed no statistically significant difference (22.11% vs. 23.43% ; p = 0.69). Conclusion: HTN prevalence was higher in the urban population than in the riverside population. Of the hypertensive individuals in both areas, <25% had controlled HTN. Comprehensive public health measures are needed to improve the prevention and treatment of systemic arterial HTN and prevent other cardiovascular diseases1271667

Prevalence And Treatment Of Hypertension In Urban And Riverside Areas In Porto Velho, The Brazilian Amazon.

Abstract Introduction: Hypertension (HTN) is a preventable cause of cardiovascular morbidity and mortality. To compare the prevalence, awareness, treatment, and control of HTN among urban and riverside populations in Porto Velho, Amazon region. We conducted a cross-sectional study between July and December 2013 based on a household survey of individuals aged 35-80 years. Interviews by using a standardized questionnaire, and blood pressure (BP), weight, height, and waist circumference measurements were performed. HTN was defined when individuals reported having the disease, received antihypertensive medications, or had a systolic BP ≥ 140 mm Hg or diastolic BP ≥ 90 mm Hg. Awareness was based on self-reports and the use of antihypertensive medications. Control was defined as a BP ≤ 140/90 mm Hg. Among the 1410 participants, 750 (53.19%) had HTN and 473 (63.06%) had diagnosis awareness, of whom 404 (85.41%) received pharmacological treatment but with low control rate. The prevalence and treatment rates were higher in the urban areas (55.48% vs. 48.87% [p = 0.02] and 61.25% vs. 52.30% [p < 0.01], respectively). HTN awareness was higher in the riverside area (61.05% vs. 67.36% ; p < 0.01), but the control rates showed no statistically significant difference (22.11% vs. 23.43% ; p = 0.69). HTN prevalence was higher in the urban population than in the riverside population. Of the hypertensive individuals in both areas, <25% had controlled HTN. Comprehensive public health measures are needed to improve the prevention and treatment of systemic arterial HTN and prevent other cardiovascular diseases.12766-7
