Pericarditis after Acute Myocardial Infarction

Abstract

a logical approach. If an insulinoma is suspected a means of confirming the diagnosis would be to take three morning plasma samples after an overnight fast. In a subject who has fasting hypoglycaemia an amended ratio of more than 50 AU/ mg, in the absence of very severe obesity, is strongly suggestive of an insulinoma, and a ratio of more than 200 ,uU/mg would appear to be diagnostic. Very occasionally patients with extreme obesity, pregnancy, or liver disease with a portosystemic shunt might give "false-positive" results; in most doubtful cases an ethanol infusion could be performed as described elsewhere (Turner et al., 1971).It has recently been shown that insulinomas secrete a high proportion of proinsulin (Melani et al., 1970a). This does not invalidate the examination of fasting insulin levels as a diagnostic measure, as a high level of immunoreactive insulin relative to the plasma glucose is the diagnostic feature-any cross-reacting proinsulin from an insulinoma would exaggerate an abnormal ratio.

Cardiac Tamponade in Dressler’s Syndrome

“…The incidence of the postmyocardial in farction syndrome or Dressler's syndrome is considered to be between 1 and 4% of all cases of myocardial infarction [1][2][3]. In addi tion to chest pain with some characteristics, 'pneumonitis' and pleural effusion, the pres ence of exudative pericarditis is a frequent component of this syndrome.…”

Pericarditis and Pericardial Effusion in Patients with Acute Myocardial Infarction

“…Finally, some workers explored the relationship between PER and post-MI (Dressler's) syndrome, while others completely ignored it [1,3,5,[8][9][10][20][21][22].…”

“…Reports of the incidence of pericarditis (PER) in pa tients with acute myocardial infarction (MI) vary greatly [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Similarly, the rate of pericardial effusion (PE) documented by echocardiography differs considerably, and the relationship of PER to PE has been variably investigated [8,9,11,15,[17][18][19].…”

“…Some of the studies of PE in patients with MI em ployed a single echocardiogram done at varying, or un specified, times after admission [8,12]; the study corre lates have been investigated to a different degree [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Some of the work was retrospective, but more recent stud ies are prospective [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”
