Brief summary
Strokes leads to significant morbidity and mortality, and hypertension is the most important risk factor for strokes. It is estimated that up to 10% of patients with hypertension have the underlying, treatable condition of primary aldosteronism. Hence, we hypothesize that the prevalence of primary aldosteronism is high in patients with strokes, a complication of long-standing hypertension. Patients admitted with an acute stroke to the Acute Stroke Unit, Changi General Hospital, will be screened for Primary Aldosteronism three months post-stroke, and confirmatory tests will be done with saline-infusion test.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of patients with stroke with confirmed primary aldosteronism in patients admitted to the acute stroke unit for stroke | 6 months | Percentage of patients with confirmed Primary Aldosteronism using confirmatory test |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Accuracy of Screening test in early period post-stroke | 3 months | To determine if the screening blood test for primary aldosteronism performed within 1 week post-stroke is equally accurate compared to being performed 2-4 months post-stroke. |
| Percentage of unilateral primary aldosteronism in patients admitted with acute stroke | 6 months | Percentage of unilateral PA amongst patients with stroke |
| Percentage of patients with positive screening test in patients admitted with acute stroke | 3 months | — |
| Blood pressure change after treatment for primary aldosteronism | 12 months | — |
| Cardiac Complications | 6 months | Cardiac complications in patients with primary aldosteronism, compared to those without primary aldosteronism, as assessed by transthoracic echocardiography features of left ventricular hypertrophy / mass, and diastolic dysfunction |
