Study Notes

Essential hypertension accounts for over 90% of high blood pressure cases, with unknown pathophysiology and genetic factors potentially playing a role.
Secondary hypertension affects less than 10% of patients and can be caused by comorbid diseases or certain drugs/products, allowing for a cure by removing the underlying cause.
Arterial blood pressure is measured in mm Hg and includes systolic (SBP) and diastolic (DBP) values, with mean arterial pressure (MAP) being important in clinical settings, calculated as (SBP × 1/3) + (DBP × 2/3).
Hormonal and neuronal regulation, along with cumulative abnormalities, can contribute to the development of essential hypertension.
Clinical presentation of hypertension may not show symptoms but can have risk factors like age, diabetes, dyslipidemia, family history of CV disease, overweight, or obesity.
Preventive programs for hypertension in Jordan are limited, with around one-third of Jordanian adults having hypertension, and awareness/control rates showing improvement but still room for enhancement.
In Jordan, poor control of hypertension is attributed to inadequate management, lack of evidence-based practices, and poor medication adherence, with older patients showing better disease awareness and control.
Hypertension complications globally contribute to millions of deaths annually, with a significant number of adults expected to suffer from hypertension-related complications by 2025.
