The Unfolded Protein Response

Endoplasmic reticulum (ER) stress, which is highly associated with cardiovascular disease, is triggered by a disturbance in ER function because of protein misfolding or an increase in protein secretion. Prolonged disruption of ER causes ER stress and activation of the unfolded protein response (UPR) and leads to various diseases. Eukaryotic cells respond to ER stress via three major sensors that are bound to the ER membrane: activating transcription factor 6 (ATF6), inositol-requiring protein 1α (IRE1α), and protein kinase RNA-like ER kinase (PERK). Chronic activation of ER stress causes damage in endothelial cells (EC) via apoptosis, inflammation, and oxidative stress signaling pathways. The alleviation of ER stress has recently been accepted as a potential therapeutic target to treat cardiovascular diseases such as heart failure, hypertension, and atherosclerosis. Exercise training is an effective nonpharmacological approach for preventing and alleviating cardiovascular disease. We here review the recent viewing of ER stress-mediated apoptosis and inflammation signaling pathways in cardiovascular disease and the role of exercise in ER stress-associated diseases.

Set Up

The endoplasmic reticulum has an intricate network of pathways built to deal with the secretory and integral membrane protein synthesis demands of the cell, as well as adaptive responses set up for the endoplasmic reticulum to rely on when stressed. These pathways are both essential and complex, and because of these 2 factors, several situations can lead to a dysfunctional endoplasmic reticulum and result in a dysfunctional cell with the potential to contribute to the progression of disease. The endoplasmic reticulum has been implicated in several metabolic, neurodegenerative, inflammatory, autoimmune, and renal diseases and disorders, and in particular, cardiovascular diseases. The role of the endoplasmic reticulum in cardiovascular disease shows how the change in function of a particular microscopic organelle can lead to macroscopic changes in the form of disease.

Normal Feature

The stage specific appearance of a retravirus, termed the Intracisternal A particle (IAP) is a normal feature of early preimplantation development. To date, all feral and laboratory strains of Mus musculus and even Asian species such as Mus cervicolor and Mus pahari express the particles during the 2-8 cell stages. IAP form by budding into the endoplasmic reticulum and appear singly or as groups of donut-shaped particles within the cisternae (fig. 1). IAP are also produced in large numbers in several neoplastic cells such as certain plasmacytomas and rhabdomyosarcomas. The role of IAP, either in normal development or in neoplastic behavior, is unknown.

Current Guidelines

The worldwide morbidity and mortality burden of cardiovascular disease (CVD) is overwhelming and caused by increasing life expectancy and an epidemic of risk factors, including hypertension. Therapeutic options targeting different areas of the renin–angiotensin–aldosterone system (RAAS) to disrupt pathophysiological processes along the cardiovascular continuum are available. Angiotensin-converting enzyme (ACE) inhibitors are first-line treatments for CVD and angiotensin receptor blockers (ARBs) are suitable alternatives. Both ACE inhibitors and ARBs prevent CVD by lowering blood pressure (BP). Additionally, several studies have demonstrated that RAAS blockade can reduce cardiovascular risk beyond what might be expected from BP lowering alone. However, the ARBs are not all equally effective. Telmisartan is a long-lasting ARB that effectively controls BP over the full 24-hour period. Recently, the Ongoing telmisartan alone and in combination with ramipril global endpoint trial (ONTARGET) study showed that telmisartan reduces cardiovascular events in high cardiovascular risk patients similarly to the gold standard ACE inhibitor ramipril beyond BP lowering alone, but with a better tolerability. Based on the results of the ONTARGET and Telmisartan randomized assessment study in ACE intolerant subjects with cardiovascular disease (TRANSCEND) studies, telmisartan is indicated for the reduction of cardiovascular morbidity. This article aims to review current guidelines for the management of CVD and consider key data from clinical trials and clinical practice evaluating the role of telmisartan in CVD.

Prevention Of Cardiovascular Disease

In Slovenia, the role of general practitioners in counselling physical activity for prevention of cardiovascular disease (CVD) is well recognized. The role of general practitioners in advising healthy lifestyle for individuals who are at risk of developing CVD is formally defined in the National Program for Primary Prevention of Cardiovascular Disease, which has been running since 2001. Part of the program is counselling on healthy lifestyle including physical activity, performed in all health centres across the country. First a screening and medical examination is performed. In case of higher risk for CVD (>20%) the physician should give advice on the particular risk factor and direct patients to health-education centres, where they can participate in healthy lifestyle workshops lead by health professionals. Physicians and other health professionals who are involved in the implementation of prevention activities within the program need knowledge and skills that are crucial for successful counselling on healthy lifestyle. The educational program “basic education in health promotion and prevention of chronic non-communicable diseases in primary health care/family medicine” consists of two parts. The first part of the training is open to all health professionals working within the program. The second part is intended for health professionals working in health-education workshops. In the last few years a new family practice model has been introduced and disseminated. Some duties of the family physician, including health promotion and counselling, are being transferred to graduate nurses who become part of the family practice team. This new division of work undoubtedly brings many advantages, both in terms of the work organization, and of high-quality patient care. Nevertheless preventive action cannot be fully passed on to graduate nurses. Careful planning and education are needed to ensure a comprehensive approach in healthy life style counselling.
