Abstract：

Objective To explore whether depressive disorder is one of risk factors for coronary artery disease (CAD) in enrolled patients and observe the level of inflammation markers in coronary artery disease patients with depression. Methods In all patients, we recoded clinical information and data from Hamilton Depression Rating Scale for Depression( HRSD)and measured concentration of monocyte chemoattractant protein-1 (MCP-1), tumour necrosis factor α (TNFα) and hypersensitive C-reaction protein (hsCRP). Results Among 87 patients with coronary artery disease, depressive disorder was diagnosed in 26 patients, the prevalence of depressive disorder was 29. 9%. Among 101 patients without coronary artery disease, 12 patients were suffering from depressive disorder, the prevalence of depressive disorder was 11.90%. The prevalence of depressive disorder in coronary artery disease group was statistically higher than that in non-coronary heart disease group (29.8% vs.11.9%, P<0. 01). The incidence of coronary artery disease was associated with age, hypertension,diabetes mellitus, hypercholesterolemia and depression. Life events and stage of heart function occurred differently between CAD patients with and without depression (P<0. 05). There were no differences in the degree of coronary artery stenosis and the type of treatment (P>0. 05) between the two groups. There were higher concentration of MCP-1 in coronary artery disease patients with depression, but no remarkable difference in hsCRP and TNFa. Conclusions There is high prevalence of depressive disorder, which is one of risk factor for coronary artery disease. The depressive disorder may be associated with inflammation biomarker in patients with coronary artery disease.     

Major depressive disorder in patients with rheumatoid arthritis

Objective

To investigate the point prevalence of major depressive disorder (MDD) as diagnosed by the Mini-International Neuropsychiatric Interview (M.I.N.I) in patients with rheumatoid arthritis (RA) and to determine whether MDD is related to features of RA disease, such as disease activity or physical dysfunction.

Methods

Of the patients with RA who participated in the IORRA survey conducted in October 2005, 162 were evaluated using the M.I.N.I., the Center for Epidemiologic Studies-Depression (CES-D) scale, and the two-question depression screen for MDD. RA clinical features were obtained from the concomitant IORRA cohort database. Relationships between MDD and RA disease features were analyzed by the Wilcoxon rank sum test and Pearson’s chi-square test.

Results

The point prevalence of MDD as diagnosed by the M.I.N.I. was 6.8 % in our Japanese patients with RA. The percentage of depressive patients was determined to be 23.5, 17.3, or 7.4 % according to the CES-D scale with cut-off points of 16, 19, or 27, respectively, and 14.2 % according to the two-question depression screen. The best cut-off point for CES-D for risk of MDD diagnosed by M.I.N.I. in this study was determined to be 23, with 11.7 % depressive patients having the highest sum of sensitivity and specificity. No relationship between MDD and RA disease activity was detected.

Conclusion

By using the well-established structural interview instrument M.I.N.I., we determined the point prevalence of MDD in the RA patients enrolled in this study to be 6.8 %, leading to the conclusion that concomitant MDD does not seem to influence disease activity in RA patients.     

Association of depressive symptoms with reduced baroreflex cardiac control in coronary artery disease

BACKGROUND: Although depression has been associated with cardiac death in coronary artery disease (CAD), little is known about the effects of depression on autonomic nervous system control of heart rate. This study evaluated whether depressive symptomatology is associated with impaired baroreflex sensitivity (BRS) in patients with CAD. METHODS AND RESULTS: BRS was assessed in 66 patients with stable CAD by using cross-spectral analysis to measure baroreceptor-mediated R-R interval oscillations. Depressive symptomatology was determined with the Beck Depression Inventory, with lower (scores <3, n = 14) and upper (scores >9, n = 16) quartiles of scores used to define groups with low and high depressive symptomatology, respectively. Comparison of the two groups showed that age-adjusted BRS was reduced in the patients with high depressive symptomatology when compared with patients with low depressive symptomatology (4.5 +/- 2.7 vs 6.5 +/- 2.8 ms/mm Hg; P <. 05). CONCLUSIONS: The current findings show that patients with CAD and depressive symptomatology have reduced BRS. Future studies are needed to examine whether reduced baroreflex cardiac control predicts cardiac risk in patients with CAD and depressive symptomatology.

Anticoagulants in coronary artery disease

Anticoagulant therapy for acute coronary syndromes is becoming more complex as newer agents are added to unfractionated heparin and warfarin. The anticoagulants used in current clinical practice are low molecular weight heparins, direct thrombin inhibitors, and heparinoids. Properties of and recent clinical trial data regarding these newer anticoagulants are reviewed in reference to current American College of Cardiology/American Heart Association guidelines.     

Echocardiography in coronary artery disease

Echocardiography has a major role in the evaluation of patients with CAD. To obtain the maximal amount of information using this technique, certain basic principles relating to regional myocardial mechanics during ischemia and flow-function relations are required. In addition, a detailed knowledge of cardiac anatomy and the three-dimensional orientation of the heart within the chest cavity is required to access meaningful information from two-dimensional planes. Furthermore, skill is also required in acquiring data in proper imaging planes and in separating true (actual pathology) from the false (artifacts, etc.). Echocardiography is not a "mature" technology. It is still developing and it is sometimes difficult to keep up with the advances. However, keeping abreast of these developments is essential to fully exploit the advantages of this technique. In addition, knowledge of the ever-changing aspects of CAD is required in order to correctly interpret visual information in context of a particular patient. Finally, more clinical studies are needed to further define the role of echocardiographic techniques in patients with CAD.     

Echocardiography in coronary artery disease

Echocardiography has come a long way since its beginnings in the early days of M-mode. Today echocardiography is a useful tool in the management and diagnosis of coronary artery disease. It is used in the emergency room to aid in the exclusion or confirmation of acute coronary syndromes and in their management. The spreading use of stress echocardiography has greatly expanded the use of ultrasound in the diagnosis and management of coronary artery disease. Both pharmacologic and nonpharmacologic methods of stress testing have added to the sensitivity and specificity of this technique, making it a viable alternative to thallium imaging for the diagnostic screening of coronary artery disease.     

Echocardiography in coronary artery disease

Coronary artery disease (CAD) is one of the major causes of morbidity and mortality. Imaging techniques represent the key method for disease extent and severity assessment and evaluation of hemodynamic complications. In skilled hands the method provides useful information for clinical management and prognosis assessment. Complex evaluation brings information about global and regional myocardial function, myocardial viability, ischemic mitral regurgitation, and about development of complications such as left ventricular thrombus formation, myocardial rupture and pericardial effusion. The main drawback of echocardiography is the limited echogenicity of many patients and its undeniable operator-dependence. However, the possibility of bringing the echocardiographic imaging to the bedside of our patients makes the method essential and its knowledge indispensable for all cardiologists.     

Post-traumatic stress disorder in patients with coronary artery disease: screening and management implications

OBJECTIVES: To review the literature on anxiety, post-traumatic stress disorder (PTSD) and depression in patients with coronary artery disease (CAD), and to present an approach to diagnosis and treatment. METHODS: MEDLINE and PsychInfo searches of English-language articles were performed. Search terms included 'anxiety', 'post-traumatic stress disorder' and 'depression', with various cardiac-related subject headings. RESULTS: Research indicates that anxiety, PTSD and depression occur frequently in patients with CAD, but these psychological problems are rarely identified or treated in the cardiology or primary care setting. CONCLUSIONS: The present review offers practical recommendations on how to detect and assess anxiety, PTSD and depression in the cardiology or primary care setting. Treatment recommendations are provided, with a focus on pharmacotherapy for anxiety and depressive disorders in patients with CAD.     

Radiation-induced coronary artery disease

Radiation-induced heart disease must be considered in any patient with cardiac symptomatology who had prior mediastinal irradiation. Radiation can affect all the structures in the heart, including the pericardium, the myocardium, the valves and the conduction system. In addition to these pathologies, coronary artery disease following mediastinal radiotherapy is the most actual cardiac pathology as it may cause cardiac emergencies requiring interventional cardiological or surgical interventions. Case A 36-year-old man was admitted to the clinic with unstable angina pectoris of one month duration. The patient had no coronary artery disease risk factor. The history of the patient revealed that he had mediastinal radiotherapy due to Hodgkin's disease at 10-year of age. Coronary arteriography showed total occlusion of the left anterior descending artery and 70% stenosis of the proximal right coronary artery. Both arteries are dilated with placement of two stents. Control coronary arteriography at the end of the first year showed patency of both stents and the patient is free of symptoms. Previous radiotherapy to the mediastinum should be considered as a risk factor for the development of premature coronary artery disease. Percutaneous transluminal coronary angioplasty with stent placement or surgical revascularization are the preferred methods of treatment. Preoperative assessment of internal thoracic arteries should be considered prior to surgery. As the radiation therapy is currently the standard treatment for a number of mediastinal malignancies, routine screening of these patients and optimal cardiac prevention during radiotherapy are the only ways to minimize the incidence of radiation-induced heart disease.     

Radiation-induced coronary artery disease

This report describes three patients who developed myocardial infarction at an untimely age, 4 to 12 years after radiation therapy for Hodgkin's disease. These cases lend credence to the cause and effect relation of such therapy to coronary artery disease.     

Total coronary occlusion in chronic coronary artery disease

The hemodynamic consequence of chronic total occlusion of a coronary artery and the association of collaterals has not been well established. To examine this, 75 patients with at least one total occlusion of a major coronary artery were identified from among 267 patients undergoing selective coronary angiography. There was evidence of previous myocardial infarction in 49 (65%) of these patients. There was no intergroup (myocardial infarction versus no infarct) difference in terms of age, chronicity of angina prior to or stability of angina at selective coronary angiography, the number and distribution of total occlusions, or the extent of coronary disease. Furthermore, there was a high prevalence of angiographically demonstrated collaterals in both myocardial infarction and noninfarct patients (96% versus 98%). However, significantly greater left ventricular dysfunction, as determined by larger end-diastolic and end-systolic volumes (p<0.001), higher left ventricular end-diastolic pressure (p<0.05), and lower ejection fraction (p<0.001) was found in the myocardial infarct group. We conclude that total occlusion of the major coronary artery occurs commonly in patients with chronic coronary disease, but is associated with myocardial infarction in only 65%. The presence of collaterals, the distribution of occlusion, and the extent of associated coronary disease do not distinguish patients with and without myocardial infarction. This suggests that the temporal course of oclusion and collateral development is a more important factor in the pathogenesis of iinfarction and its hemodynamic consequences.     

Atypical or nonanginal chest pain. Panic disorder or coronary artery disease?

Of 195 patients with atypical or nonanginal chest pain presenting in a cardiology clinic, 104 consented to be evaluated for anxiety disorders using a structured psychiatric interview. Thirty patients had histories of coronary artery disease (CAD). Fifty-nine patients in the sample (16 of those with CAD and 43 of those without CAD) fit diagnostic criteria for panic disorder (PD). Those without CAD and with PD were primarily women (mean age, 43 years) with predominantly nonanginal chest pain. Those patients with both CAD and PD were primarily men (mean age, 54 years) with predominantly atypical angina. Since PD has been shown to be readily responsive to pharmacologic intervention, this diagnosis should be considered in patients with atypical or nonanginal chest pain.     

HIV-associated coronary artery disease

Cases, case series, and related articles on coronary artery disease in patients with human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) identified through a comprehensive literature search were examined for clinical characteristics and angiographic findings of HIV-associated coronary artery disease. Among 129 identified cases, 91% were males. The mean age was 42.3 +/- 10.2 (SD) years (range, 23 to 77 years). The interval between the diagnosis of HIV infection and the diagnosis of coronary artery disease was 72 +/- 60 (SD) months. Degree of immunosuppression was variable (CD4 mean, 313 +/- 209 cells/mm3; range, 6-1070 cells/mm3). There was no correlation between the CD4 cell count and the development and progression of coronary artery disease. Similarly, the development and progression of coronary artery disease was independent of the presence of HIV-related opportunistic infections. Acute myocardial infarction was the initial presentation in 77% of patients. In 76 patients, information on diseased vessels was available: 36 (47%) patients had 3-vessel disease, 14 (18%) patients had 2-vessel disease, and 26 patients (35%) had 1-vessel disease. The left anterior descending artery was involved in 47 (62%) patients while the left circumflex and right coronary arteries were involved in 34 (45%) and 38 (50%) patients, respectively. Thirty-two (25%) patients underwent catheter-based or surgical revascularization. Data were not adequate to assess the prognosis following the acute coronary events or revascularization. The histologic characteristics unique to HIV-associated coronary arteriopathy were diffuse circumferential involvement of the vessel with an unusual proliferation of smooth muscle cells, mixed with abundant elastic fibers, resulting in endoluminal protrusions. Coronary artery disease was a late complication of AIDS.     

Aneurysmal coronary artery disease

To examine the clinical and historical features and the natural history of aneurysmal coronary disease, we reviewed the registry data of the Coronary Artery Surgery Study (CASS). Nine hundred seventy-eight patients, representing 4.9% of the total registry population, were identified as having aneurysmal disease. No significant differences were noted between aneurysmal and nonaneurysmal coronary disease patients when features such as hypertension, diabetes, lipid abnormalities, family history, cigarette consumption, incidence of documented myocardial infarction, presence and severity of angina, and presence of peripheral vascular disease were examined. In addition, no difference in 5-year medical survival was noted between these two groups. These findings suggest that aneurysmal coronary disease does not represent a distinct clinical entity but is, rather, a variant of coronary atherosclerosis.
