Resumen
El control de la presión arterial (PA) en adultos estadounidenses mejoró inicialmente, pero luego disminuyó. Esta tendencia pone de relieve la necesidad de seguir esforzándonos en el tratamiento de la hipertensión para reducir el riesgo de enfermedades cardiovasculares.
Área de la Ciencia:
- Epidemiología de las enfermedades cardiovasculares
- Vigilancia de la salud pública
- Manejo de la hipertensión
Sus antecedentes:
- El control de la presión arterial (PA) es crucial para reducir el riesgo de enfermedad cardiovascular (ECV).
- La hipertensión afecta a una parte significativa de la población adulta en los Estados Unidos.
Objetivo del estudio:
- Para analizar las tendencias en el control de la presión arterial entre adultos estadounidenses con hipertensión de 1999-2000 a 2017-2018.
- Identificar los factores demográficos y de salud relacionados con el control de la presión arterial.
Principales métodos:
- Análisis transversal en serie de los datos de la Encuesta Nacional de Salud y Nutrición (NHANES).
- Inclusión de 18,262 adultos estadounidenses con hipertensión en 10 ciclos de encuesta (1999-2018).
- Control de la presión arterial definido como presión arterial sistólica < 140 mm Hg y presión arterial diastólica < 90 mm Hg.
Principales resultados:
- La proporción ajustada por edad de adultos con presión arterial controlada aumentó del 31,8% en 1999-2000 al 48,5% en 2007-2008, luego disminuyó al 43,7% en 2017-2018.
- La presión arterial controlada fue menos probable en los adultos negros no hispanos en comparación con los adultos blancos no hispanos.
- El acceso al seguro de salud y a un centro de atención médica habitual se asoció con tasas más altas de control de la presión arterial.
Conclusiones:
- El control de la presión arterial entre los adultos estadounidenses con hipertensión mostró un aumento inicial seguido de una disminución significativa.
- Existen disparidades en el control de la presión arterial entre grupos raciales/étnicos y estados socioeconómicos.
- Son necesarios esfuerzos sostenidos de salud pública para mejorar y mantener el control de la hipertensión en todo el país.

01:28Hypertension I: Introduction
528
Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...

Several physiological and lifestyle factors influence blood pressure (BP). Understanding these factors is crucial as they are significant in patient education and blood pressure management.

01:18Hypertension and Regulation of Blood Pressure
3.5K
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

3.8K
Blood pressure (BP) is the pressure or force of blood exerted on the artery's walls as it circulates through the body. It is essential for maintaining blood flow throughout the body.
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the...

The movement of blood in a human body, commonly referred to as blood flow, is determined by the volume of blood that traverses a certain section of the bodily system per unit time. It is the rhythmic contraction of the heart's ventricles that primarily instigates this movement. As the ventricles contract, blood is forced into the prominent arteries, which then flow from areas of greater pressure to lower pressure areas. This movement continues into smaller arteries and arterioles and...

Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...
