Brief Summary

Sudden Cardiac Death is a leading cause of mortality and remains a major public health burden worldwide. Cardiac arrest due to coronary heart disease explains a large proportion of the cases, but if autopsy is not performed the exact underlying cause remains obscure in many adults who face sudden death outside heath care organizations. The investigators aim to find proof that primary aldosteronism is a risk factor for sudden death and to characterize the prevalence of adrenal pathology in sudden death of undetermined cause in a case-control study. In addition, the study aims to characterize the prevalence of other adrenal pathology i.e. silent adenomas, cortisol-producing adenomas and pheochromocytomas in sudden death. The investigators also seek evidence that other endocrine hormone overproduction-causing diseases are more prevalent in persons with sudden death compared with those experiencing traumatic or suicidal death sudden death.

Study Arms (2)

Sudden death

Unexpected witnessed death occurring within an hour of the onset of symptoms in a person with or without previously known cardiac disease without an extra-cardiac cause, or unexpected unwitnessed death without extra-cardiac cause occurring in the previous 24 hours

Diagnostic Test: Adrenal aldosterone synthase (CYP11B2) stainingDiagnostic Test: Adrenal cortisol synthase (CYP11B1) stainingDiagnostic Test: Histopathological analysis

Control

Death because of an exogenic reason for sudden death such as trauma or suicide as a control group i.e. non-disease-induced sudden death

Diagnostic Test: Adrenal aldosterone synthase (CYP11B2) stainingDiagnostic Test: Adrenal cortisol synthase (CYP11B1) stainingDiagnostic Test: Histopathological analysis

Interventions

Immunoshistochemical diagnosis of primary aldosteronism

ControlSudden death

Immunoshistochemical diagnosis of adrenal hypercortisolism

ControlSudden death

Diagnosis of any endocrine neoplasia other than primary aldosteronism or adrenal hypercortisolism

ControlSudden death

Sampling MethodProbability Sample
Study Population

We enroll aproximately 200 consecutive patients with out-of-hospital, sudden death to both groups.

You may qualify if:

  • Consecutive patients with out-of-hospital, sudden death

You may not qualify if:

  • Estimated time from death to refrigerator more than 24-48 hours and in the refrigerator time more than 7 days (susceptibility to excessive tissue breakdown)
  • Terminal disease
  • Institutionalized patients
