ADVICE

Empathy Improves Medication Adherence

Build trust and empathy to improve medication adherence; patients are likelier to take medicines when they feel cared for.
Prioritize listening to a patient's story rather than rigidly chasing guideline numbers.

INSIGHT

Blood Pressure Is A Continuous Risk

Hypertension is a graded risk, not a binary disease, and risk rises continuously with higher blood pressure.
Epidemiology uses thresholds (e.g., 130/80) for action, but harm begins above ~115 systolic.

INSIGHT

Why High Blood Pressure Damages Organs

High blood pressure forces the heart to work harder and eventually leads to heart failure when it can no longer compensate.
Major target organs are heart, brain, and kidneys which suffer different pressure-related injuries.
