All-cause mortality, CVD, and cancer mortality were highest in the low-DBP group (<75 mm Hg). Thus, comorbidities such as cancer and thus low weight and hypotension were the confounding factors that obscured the true relationship of BP and mortality.

1. LA CURVA J ESTA PRESENTE EN MUCHOS ESTUDIOS DE HIPERTENSION ARTERIAL RELACIONANDO MORTALIDAD CARDOVASCULAR CON PRESION DIASTOLICA
2. LA CURVA J ES MAS COMUN EN PACIENTES CON ENFERMEDAD
ATEROSCLEROTICA AVANZADA 3. LA CAUSA DE ESTA CURVA ES AUN CONTROVERSIAL PORQUE LOS ESTUDIOS
NO HAN SIDO DISEÑADOS EXPRESAMENTE PARA ESTUDIAR ESTA RELACION 4. DEBE BUSCARSE REDUCIR LA PRESION SISTOLICA DEBAJO DE 140 mmHg Y LA DIASTOLICA DEBAJO DE 90 mmHg EN LOS PACIENTES DE ALTO RIESGO SIN IR “ MAS BAJO MEJOR”
