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.

Primary Outcome Measures :
  1. Percentage of patients with stroke with confirmed primary aldosteronism in patients admitted to the acute stroke unit for stroke [ Time Frame: 6 months ]
    Percentage of patients with confirmed Primary Aldosteronism using confirmatory test


Secondary Outcome Measures :
  1. Accuracy of Screening test in early period post-stroke [ Time Frame: 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.

  2. Percentage of unilateral primary aldosteronism in patients admitted with acute stroke [ Time Frame: 6 months ]
    Percentage of unilateral PA amongst patients with stroke

  3. Percentage of patients with positive screening test in patients admitted with acute stroke [ Time Frame: 3 months ]
  4. Blood pressure change after treatment for primary aldosteronism [ Time Frame: 12 months ]
  5. Cardiac Complications [ Time Frame: 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
