This study has assessed whether chest pain occurring during or after a step test could improve the accuracy of exercise testing in the diagnosis of coronary artery disease (CAD). One hundred and fifty-three consecutive men underwent the double Master two-step test prior to diagnostic coronary arteriography. On hundred and twenty-five had CAD, 28 insignificant disease (NCA). The post-exercise ECG showed at least 0-5 mm of ischaemic ST depression in 71 (57%) of the men with CAD and in five (18%) with NCA. Ischaemic ST depression of at least 2-0 mm occurred in 24 men, all of whom had CAD. Chest pain occurred during or after the test in 78 (62%) men with CAD and in nine (33%) with NCA. The accuracy of diagnosis of CAD could be improved by combining the occurrence of chest pain in the test with a positive post-exercise ECG. Either a 2 mm positive post-exercise ECG with or without test angina or 0-5 mm to 1-9 mm positive post-exercise ECG with test angina was found in 56 (45%) of men with CAD and one (4%) with NCA. Thus the concurrence of chest pain during or after a double Master two-step test, together with ischaemic ST segment depression after the test, strongly suggests the presence of CAD.

Patients with non-fear panic disorder (NFPD) meet DSM-III-R criteria for panic disorder, but do not report subjective fear or anxiety. Although apparently common in medical settings, this controversial group is in need of further diagnostic validation. This study assessed family history of panic disorder in patients with chest pain and normal coronary arteries (CP/NCA) and either NFPD, panic disorder with fear, or no panic. It was hypothesized that the two panic disorder groups would have similar, elevated rates of panic disorder in their first-degree relatives, compared to patients without panic. The results support the hypothesis; about 17% of the first-degree relatives of both NFPD and panic disorder patients were diagnosable with panic disorder according to proband interviews, whereas only 4.6% of the first-degree relatives of patients without panic were so diagnosable. These results support the diagnostic validity of NFPD in CP/NCA patients, because such patients had a family history of panic disorder similar to patients with a more classical panic disorder presentation. The lack of fear symptoms and behavior in NFPD may cause panic disorder to be overlooked as a potential cause of somatic symptoms in patients with no medical explanation for their condition.

We have quantified levels of CD105, its ligand TGFbeta and receptor-ligand complexes in sera from healthy individuals (n=31), patients with triple vessel disease documented by coronary angiography (TVD; n=36) and patients with chest pain and a positive exercise electrocardiogram but with normal coronary angiogram (NCA; n=30). Both active TGFbeta1 and active plus acid-activatable TGFbeta1 [(a+l)TGFbeta1] were significantly depressed in patients with TVD compared with the other two groups (P</=0.04). CD105 levels in TVD patients were also diminished but elevated in NCA patients. In contrast, patients with TVD had more CD105/TGFbeta1 complex in their sera than the other two groups, suggesting that this may be the reason why TVD patients had low levels of receptor and ligand. TGFbeta3 levels were similar in the three groups, but elevated CD105/TGFbeta3 levels were noted in patients with NCA compared with those with TVD and healthy individuals (P< or =0.02). CD105 was correlated with both active TGFbeta1 and (a+l)TGFbeta1 (P=0.02). CD105 also strongly correlated with TGFbeta3 and CD105/TGFbeta3 complexes (P=0.001 in both cases). The changes in levels of CD105, TGFbeta1 and the receptor-ligand complexes in sera of patients with atherosclerosis suggest that these molecules may be important in the pathobiology of the atherosclerotic disease. Further studies on sequential samples from a larger cohort of patients are needed to define a causal relationship between these molecules and the disease progression.
