The Association of Iron Intake and Hypertension, Does Iron Intake Decrease Blood Pressure?

Previous studies reported that iron may have an indispensable role in the risk of hypertension (HTN). However, the result of the studies on the relationship between iron and risk of HTN is inconsistent. This study aimed to assess the association between the association of dietary iron intake and HTN in the Iranian population. This case-control study was conducted on 4184 people aged 35 to 70, including 1239 people with HTN and 2945 people with normal blood pressure (BP) in Sabzevar, Iran. Dietary intake was assessed using a food frequency questionnaire (FFQ). The Nutritionist IV software was used in terms of the assessment of dietary intake of iron. An inverse association was found between iron intake and HTN (OR = 0.97, CI 95%: 0.94-0.99, P = 0.04). The association remained significant after adjustment for age, gender, smoking, drinking alcohol, calorie intake, and BMI (OR = 0.94, CI 95%: 0.89-0.98, P = 0.01). As a conclusion, iron intake was inversely associated with HTN. Further longitudinal studies on the effect of iron intake on BP are required to confirm this finding.

Blood pressure levels post mechanical thrombectomy and outcomes in non-recanalized large vessel occlusion patients.

OBJECTIVE: Permissive hypertension may benefit patients with non-recanalized large vessel occlusion (nrLVO) post mechanical thrombectomy (MT) by maintaining brain perfusion. Data evaluating the impact of post-MT blood pressure (BP) levels on outcomes in nrLVO patients are scarce. We investigated the association of the post-MT BP course with safety and efficacy outcomes in nrLVO. METHODS: Hourly systolic BP (SBP) and diastolic BP (DBP) values were prospectively recorded for 24 hours following MT in consecutive nrLVO patients. Maximum, minimum, and mean BP levels were documented. Three-month functional independence (FI) was defined as modified Rankin Scale (mRS) scores of 0-2. RESULTS: A total of 88 nrLVO patients were evaluated post MT. Patients with FI had lower maximum SBP (160±19 mmHg vs 179±23 mmHg; P=0.001) and higher minimum SBP levels (119±12 mmHg vs 108±25 mmHg; P=0.008). Maximum SBP (183±20 mmHg vs 169±23 mmHg; P=0.008) and DBP levels (105±20 mmHg vs 89±18 mmHg; P=0.001) were higher in patients who died at 3 months while minimum SBP values were lower (102±28 mmHg vs 115±16 mmHg; P=0.007). On multivariable analyses, both maximum SBP (OR per 10 mmHg increase: 0.55, 95% CI 0.39 to 0.79; P=0.001) and minimum SBP (OR per 10 mmHg increase: 1.64, 95% CI 1.04 to 2.60; P=0.033) levels were independently associated with the odds of FI. Maximum DBP (OR per 10 mmHg increase: 1.61; 95% CI 1.10 to 2.36; P=0.014) and minimum SBP (OR per 10 mmHg increase: 0.65, 95% CI 0.47 to 0.90; P=0.009) values were independent predictors of 3-month mortality. CONCLUSIONS: Our study demonstrates that wide BP excursions from the mean during the first 24 hours post MT are associated with worse outcomes in patients with nrLVO.

Aspectos clínico-epidemiologícos de la presión arterial en población pediátrica del eje centro norte costero de Venezuela evaluada en el SENACREDH: III: variables antropométricas y bioquímicas asociadas a la presión arterial / Clinical epidemiological aspects of the blood pressure in a paediatric population from the venezuelan central north seaside axis evaluated in the SENACREDEH: III: anthropometrical and biochemical variables associated to the blood pressure

En el contexto del Segundo Estudio Nacional de Crecimiento y desarrollo Humano de la República Bolívariana de Venezuela (SENACREDH), se evaluó la presión arterial en 4017 individuos de 6,00 a 19,99 años en los estados Carabobo, Aragua, Miranda, Vargas y Distrito Capical. Se realizaron modelos de regresión múltiple con variables antropométricas y bioquímicas como predictoras de la presión arterial. La prevalencia de valores de presión arterial mayor igual P90 (Pre-hipertensión arterial e hipertensión arterial) sistólica fue 4,36% y la diastólica aislada fue 4,62%. Aquellos con exceso de índice de masa corporal presentaron prevalencias significativamente mayores de presión arterial sistólica, P90 a <95 (6,3%), P95 a igual P99 (0,9%) en comparación con aquellos con indice de masa corporal normal P90 a <95(1,2%), P95 a <99 (0,7%), > igual P99 (0,3%). Se encontraron resultados similares para la presión arterial diastólica. Aquellos con índice colesterol total/HDL > igual 4,0 presentaron prevalencias significativamente mayores de presión arterial sistólica, P90 a <95 (3,1%), P95 a < P99 (1,7%), > igual P99 (0,6%) en comparación con aquellos con < 4,0 P90 a < P95 (1,7%), P95 a > P99 (1,1%), > igual P99 (0,3%). Se encontraron resultados similares para la presión arterial diastólica. En la regresión múltiple, el índice de masa corporal y la circunferencia de cintura son predictores de la presión arterial sistólica (P<0,001). La circunferencia de cintura lo es también para la presión arterial diastólica (P<0,001). Estas variables se asocian significativamente como predictores de la presión arterial, por lo cual su medición en la evaluación integral cardiovascular debe realizarse no solo para efectos de clasificación sino de potencial estimación del riesgo de hipertensión arterial.

In the context of the Second National Study of Human Growth and Development of the Bolivarian Republic, of Venezuela (SENACREDH), blood pressure was evaluated in 4017 individuals 6.00 to 19.90 years-old from Carabobo, Aragua, Miranda, Vargas state and Capital District. Multiple regression models with anthropometrical and biochemical variables for the blood pressure were done. Prevalence of isolated blood pressure > igual P90 (Prehypertension and hypertension) systolic was 4.36% and diastolic 4.62%. Those with body mass index in excess presented significantly higher prevalences of systolic blood pressure. P90 to igual P99 (0.9%) compared to those with a normal body mass index P90 to igual P99 (0.3%). Similar findings were found for diastolic blood pressure. Those with a total cholesterol/HDL index > igual 4.0 presented significantly higher prevalences of systolic blood pressure, P90 to igual P99 (0.6%) compared to those with <4.0 P90 to igual P99 (0.3%). Similar findings were found for diastolic blood pressure. At multiple regression body mass index and waist circumference are predictor of systolic blood pressure (P<0.001). Waist circunference also for diastolic blood pressure (P<0.001). These variables are significantly associated as predictors of blood pressure, then its assessment in the untegral cardiovascular evaluation should be done not just for classification but also as potential risk estimation for hypertension.

Amlodipin to treat high blood pressure in pregnant intoxication

The results of treatment of high blood presure in pregnant intoxication on 61 pregnant women are as follows: success rate 54/61 (88.52%). Systolic blood pressure and diastolic blood pressure decreased significantly in comparing with the use of Aldomet in combining with Hydralazin (p 0.05), uremia decreased significantly. For the fetus, Apgar index was tolerable, no sign of monster and stillbirth. Conclusion: Amlodipin is good drug for treating high blood pressure in pregnant intoxication.
