Abstract
The prevalence of coronary heart disease (CHD) and associated manifestations with ischaemic resting electrocardiogram (ECG) changes, clinical findings and sociodemographic factors were studied in 1990–1991 among an elderly population in southwestern Finland. One of the specific
aims was to describe the health-related quality of life of elderly coronary heart disease patients, i.e. the associations between CHD and physical, psychological, cognitive and social functioning. 488 men and 708 women aged 64 years and over (93% of those eligible) participated in this cross-sectional epidemiological survey in the rural district of Lieto. The participants were examined and interviewed during two visits to the local health centre. An ECG and a chest x-ray were taken and a clinical examination was made by a doctor. The Rose questionnaire was used to determine the prevalence of angina pectoris (AP). The Minnesota codes were used in the analyses of ECG findings. The medical records were reviewed.
The prevalence of AP was 9.1% (95% Confidence Interval 6.7–12.0) among men and 4.9% (3.5–6.8) among women. The respective figures for past myocardial infarction (MI) (based on the medical records or a major or moderate Q/QS item on ECG, codes 1.1–1.2) were 13.9% (10.9–17.0) and 6.5% (4.8–8.6). Ischaemic ECG findings (codes 1.1–1.3, 4.1–4.4, 5.1–5.3, 7.1) were common: 32.9% (28.7–37.1) of men and 39.3% (35.7–43.0) of women had such changes. The total prevalence of CHD, including AP, MI, past coronary bypass surgery or angioplasty or ischaemic ECG findings, was 37.7% (33.4–42.0) in men and 42.0% (38.3–45.6) in women.
The patients and controls were mainly aged, non-institutionalized, community-living persons. The patients with CHD (AP and/or a past MI) had more difficulties in physical functioning than their age- and sex-matched controls. According to logistic regression analyses, CHD was not independently associated with difficulties in physical functioning. However, physical disability was associated with the use of cardiovascular drugs and also with old age, the use of psychotropic drugs, depression and cancer. More male patients than controls had depression measured on the Zung Self-Rating Depression Scale. The depression had often gone undiagnosed, especially among men. Among men, the most important factors associated with depression were difficulties in physical functioning and widowhood or divorce, while among women, previous depression and the use of ACE inhibitors emerged as significant. There were no differences between the patients and controls in cognitive functioning. The male patients had a higher frequency in visiting activity than the controls. Old age, difficulties in physical functioning, CHD and chronic obstructive pulmonary disease were associated with impaired social functioning.
In conclusion, CHD is common in the Finnish elderly. The clinical picture of CHD in elderly people is varying. It seems that CHD has no independent impact on functional disability in the elderly. Old age, sociodemographic factors, medication and other chronic diseases are also contributors.

Encapsulation of Cardiac Stem Cells to Enhance Cell Retention and Cardiac RepairMayfield, Audrey January 2014 (has links)
Despite advances in treatment, heart failure remains one of the top killers in Canada. This recognition motivates a new research focus to harness the fundamental repair properties of the human heart, with human cardiac stem cells (CSCs) emerging as a promising cell candidate to regenerate damaged myocardium. The rationale of this approach is simple with ex vivo amplification of CSCs from clinical grade biopsies, followed by delivery to areas of injury, where they engraft and regenerate the heart. Currently, outcomes are limited by modest engraftment and poor long-term survival of the injected CSCs due to on-going cell loss during transplantation. As such, we explored the effect of cell encapsulation to increase CSC engraftment and survival after myocardial injection. Transcript and protein profiling of human atrial appendage sourced CSCs revealed strong expression the pro-survival integrin dimers αVβ3 and α5β1- thus rationalizing the integration of fibronectin and fibrinogen into a supportive intra-capsular matrix. Encapsulation maintained CSC viability and expression of pro-survival transcripts when compared to standard suspended CSCs. Media conditioned by encapsulated CSCs demonstrated superior production of pro-angiogenic/ cardioprotective cytokines, angiogenesis and recruitment of circulating angiogenic cells. Intra-myocardial injection of encapsulated CSCs after experimental myocardial infarction favorably affected long-term retention of CSCs, reduced scar burden and improved overall cardiac function. Taken together, cell encapsulation of CSCs prevents detachment induced cell death while boosting the mechanical retention of CSCs to enhance repair of damaged myocardium.

A Collagen Matrix Promotes Anti-Inflammatory Healing Macrophage Function Through a miR-92a MechanismLister, Zachary January 2016 (has links)
MicroRNAs are emerging as key players in the regulation of the post-myocardial infarction (MI) environment. We previously identified that matrix-treated hearts had down-regulated expression of miR-92a, a miRNA with inflammatory and migratory effects that is normally up-regulated after MI. We have shown that type I collagen matrix treatment at 3h post-MI leads to less inflammation and improved cardiac function, but the underlying mechanisms remain to be better characterized. The goal of this study was to elucidate a possible role of miR-92a in the anti-inflammatory/pro-wound healing effect of matrix treatment post-MI. C57BL/6J mice underwent LAD ligation to induce MI. Hearts were removed at 4h, 1d, 3d, and 7d post-MI and RNA was extracted from infarct and peri-infarct tissue. PCR analysis revealed that hearts injected with matrix at 3h post-MI resulted in significantly decreased miR-92a at 4h, 1d, and 3d compared to non-injected animals at each time point (p<0.0001) and PBS injected animals at 4h and 7d (p<0.004). Several targets of miR-92a and regulators of macrophage polarization were found to be up-regulated (p<0.05) early in MI indicating early amelioration of inflammatory processes. In vitro, macrophages cultured on matrix also had decreased expression of miR-92a compared to cultures on tissue culture poly styrene (TCPS) (p<0.001). Integrins α5 (ITGAα5) and αV (ITGAαV), involved in cell-matrix interactions, as well as inflammatory regulators S1PR1 and SIRT1 were identified as putative miR-92a targets. When miR-92a is over-expressed in macrophages, ITGα5 (p=0.0002), ITGαV (p=0.02), and S1Pr1 (p<0.0001), and SIRT1 (p=0.03) all had decreased expression. STAT3 and IL-10 were found to be moderately down-regulated. In evaluating macrophage phenotypes, M2 macrophages had reduced miR-92a expression on matrix compared to M1 macrophages. The migration of M2 macrophages into the matrix is increased compared to M1 macrophages. We report that the beneficial effects of matrix treatment post-MI may be mediated, at least in part, through its ability to regulate miR-92a and pro-wound healing mechanisms in macrophages. These results present the matrix as a novel non-pharmacological approach to locally regulate miRNAs in vivo for reducing inflammation and protecting the myocardium post-MI.

Effects of Extracellular Matrix Glycation on Cell and Tissue FunctionNadlacki, Borivoje Bora January 2017 (has links)
Methylglyoxal (MG) is a reactive dicarbonyl derived as a by-product of glycolysis. If MG is not metabolized by glyoxalase-1 (Glo1), it glycates macromolecules producing advanced glycation end products (AGEs); these have been linked to larger infarct sizes and poorer cardiac function after myocardial infarction (MI). Proteins of the extracellular matrix (ECM) are prime targets for glycation by MG, but it is unknown if MG modification of the ECM may be a mechanism that contributes to the poor repair and function of the post-MI heart. This study sought to examine if MG-induced modifications of ECM proteins negatively affect fibroblast and endothelial cell function. Analysis with an MG-derived hydroimidazolone 1 (MG-H1) antibody confirmed MG modification of laminin and collagen type (Col) 1, 3, and 4. MG modifications decreased endothelial cell (EC) adhesion on Col3, Col4, and laminin and angiogenesis on ECMatrix. Furthermore, alpha smooth muscle actin staining indicated increased myofibroblast differentiation of fibroblasts on MG-modified proteins. Following induction of MI, extracted mouse hearts were decellularized and compared to healthy controls. Perhaps a result of technical challenges, both western blot and immunohistochemistry contrasted previous data by displaying a marked decrease in MG-H1 modifications post-MI. Overall, these results indicate that MG modifications of the ECM negatively influence EC and fibroblast function, requiring more research on their impact in cardiovascular disease progression.
