Clinical features

Why?

Sweating makes a myocardial infarction more likely

Patient	Target Disorder and Reference Standard	Diagnostic Test	LR+ (95% CI)	Post-test Probability	LR- (95% CI)	Post-test Probability
anterior chest pain b (pre-test probability: 12%)	myocardial infarction (cardiac enzymes, ECG)	history of sweating	2.5 (2.0 to 3.3)	26%	0.52 (0.38 to 0.71)	7%

Note:

• Classic cardiac risk factors (smoking, hypertension, diabetes, etc) are not clearly helpful at diagnosing a myocardial infarction. ^b
