Knowledge and Recommendations of Dietary Supplements by Healthcare Professionals to Treat Patients Post-Cardiac EventDeming, Elise 01 August 2018 (has links) (PDF)
Cardiovascular disease and cardiac events are common and serious health conditions in the United States. Nutrition therapy can play a significant role in the management and treatment of cardiovascular disease, which includes cardiac events. This study examined the dietary supplement knowledge and recommendations made by registered dietitians (RDs), cardiologists, physician assistants, and nurse practitioners to treat patients after experiencing a cardiac event. Over 75 cardiologists, physician assistants, and nurse practitioners in the Tricities area of Tennessee and 3,000 RDs nationwide were asked to complete a 15-question web-based survey. Over 280 RDs and only one cardiologist responded. Findings suggest RDs are aware of evidence supporting dietary supplementation in the treatment of general heart health and cardiac events. Additionally, RDs make dietary supplement recommendations as treatment for patients who have experienced a cardiac event, specifically omega-3 fatty acids or fish oil, coenzyme Q10, and plant sterols.

Promoting self-management for patients with type 2 diabetes following a critical cardiac eventWu, Chiung-Jung January 2007 (has links)
Type 2 diabetes is a global health problem. Evidence indicates that type 2 diabetes can lead to serious complications, such as a cardiac event, which usually require critical nursing care. Patients with type 2 diabetes and with a history of cardiac disease are at greater risk of a further cardiac event requiring readmission to hospital.
Evidence indicates that improved diabetes management assists patients with type 2 diabetes to manage their condition efficiently, reduces risks of a further cardiac event, and therefore reduces hospitalisations. However, there is limited information found regarding a diabetes management program specifically for patients who have already had cardiac complications. Difficulties in developing patients' skills in managing and modifying their daily lives also present a challenge to coronary care staff. Therefore, there is a real need to develop a special diabetes management program for patients with diabetes who have experienced a critical cardiac event, which will be commenced in the Coronary Care Unit (CCU).
The aim of this research is to gain a greater understanding of the characteristics, secondly to obtain in-depth understanding of needs and experiences of patients with type 2 diabetes hospitalised for a critical cardiac event. A further aim is to develop and pilot test a diabetes management program, specific to the patients with diabetes in the context of the CCU.
The design of this research employed three studies: Study I was an exploratory study, which obtained patients' demographic and disease characteristics from the hospital records of all patients with diabetes admitted to the CCU of one public hospital between 1 January 2000 to 31 December 2003. Study II used a qualitative interpretative approach and aimed to gain an in-depth understanding of the perspectives of patients with type 2 diabetes who have experienced a critical cardiac event in managing their everyday lives with both diabetes and cardiac conditions. Study III included two parts. The first utilised the information from the first two studies and the literature (self-efficacy theory) to develop a diabetes self-management program specifically for patients with diabetes who have had a critical cardiac event. The second part pilot tested the newly-developed diabetes self-management program for patients with diabetes admitted to CCU following a critical cardiac event. The pilot study used a randomised controlled trial research design to evaluate the efficacy of the program.
Study I collected data from one hospital's records retrospectively from 2000 to 2003. The results of Study I showed there were 233 (14.7%) patients admitted to CCU that had diabetes out of the total 1589 CCU admissions during the study period. More than 22% of CCU patients with diabetes were readmitted to hospital within 28 days, compared to 6% of CCU patients without diabetes. Patients with diabetes who had a longer CCU stay were more likely to be readmitted. These results indicate that a significant proportion of a CCU population had type 2 diabetes and is more likely to be readmitted to hospital.
Study II used an interpretive approach comprising open-ended interviews to collect data from patients with type 2 diabetes experiencing a cardiac event who had a CCU admission in 2000-2003. The findings revealed that patients with diabetes who had a critical cardiac event experienced considerable feelings of hopelessness and fatigue. Patients also had concerns in the areas of self-confidence and confidence in health professionals. Patients indicated that greater self-confidence and confidence in health professionals would help their ability to manage their daily lives. Therefore, it is very important that intervention programs for these at-risk patients need to improve patients' confidence levels, and reduce their feelings of hopelessness and fatigue.
The information gathered from Study I and Study II provided important insight into the development of an effective diabetes self-management specifically designed for patients with type 2 diabetes following a critical cardiac event, which is presented in Study III in this thesis. Study III also provided a preliminary evaluation of the newly developed program. The evaluation used a randomised controlled trial research design for the new program and the current educational program provided in the CCU. The results of the program indicate the feasibility of commencing the new diabetes self-management program in the CCU, and to be continued in wards or at home. The results also showed significant improvements in patients' knowledge in the experimental group, but not in other outcome variables (self-efficacy, vitality and mental health levels). However, as a small sample size was used in this pilot study, a larger study is needed to ensure adequate testing of the intervention. Future research is also recommended to incorporate the new diabetes self-management program into the current cardiac education program. Staff's further professional development in providing such a program also needs to be examined. Improvements in quality of care, and patients' quality of life are expected in the future.

Études de conditions favorisant la prévention de la contrainte et des maladies cardiovasculaires chez les pompiersGendron, Philippe 10 1900 (has links)
Représentant 43% des décès rapportés au cours des dix dernières années, la mort subite due à un événement cardiaque est la cause de décès au travail la plus fréquente chez les pompiers américains. Des études démontrent que le risque d’événements cardiaques au travail chez les pompiers est accentué par deux causes principales, la première étant la présence d’une maladie coronarienne, d’une cardiomégalie/hypertrophie ventriculaire gauche (HVG) ou de dommages occasionnés antérieurement par un infarctus du myocarde, la seconde étant l’importante contrainte cardiovasculaire subie au travail.
Aucune étude n’a été réalisée pour évaluer l’état de santé cardiovasculaire des pompiers et pompières du Québec. Une telle étude permettrait d’en connaître davantage sur leur risque de maladies et d’événements cardiovasculaires. Par ailleurs, on constate que la prévalence des facteurs de risque des maladies cardiovasculaires (MCV) est élevée chez les pompiers américains, ce qui corrèle avec le nombre élevé d’événements cardiaques au travail. Le premier objectif de cette thèse était donc de dresser un portrait de la santé cardiovasculaire des pompiers et pompières du Québec.
Ensuite, dans le but de réduire le risque d’événements cardiaques au travail, il était pertinent d’étudier une stratégie de prévention des MCV chez les pompiers. Le risque de développer une maladie coronarienne ou une cardiomégalie/HVG pourrait être réduit en adoptant et maintenant de saines habitudes de vie, dont une pratique régulière d’activités physiques. Plusieurs services de sécurité incendie au Québec permettent aux pompiers de faire du conditionnement physique en caserne pendant les heures de travail. Cette pratique pourrait contribuer à augmenter leur quantité d’activités physiques hebdomadaire et à améliorer leur santé cardiovasculaire. Le deuxième objectif de cette thèse était donc de comparer la pratique d’activités physiques hebdomadaire et différents indicateurs de santé cardiovasculaire chez les pompiers qui font et ceux qui ne font pas de conditionnement physique pendant les heures de travail.
Enfin, dans le but de réduire le risque d’événements cardiaques au travail, il semblait pertinent de s’intéresser à la prévention de la contrainte cardiovasculaire subie au travail chez les pompiers, considérant qu’elle agit comme « déclencheur ». Cette contrainte pourrait être réduite en évitant d’écourter les périodes de repos octroyées entre les phases de travail lors d’une intervention. Le troisième objectif de cette thèse était de comparer et de caractériser la contrainte cardiaque engendrée par deux interventions simulant les tâches du métier de pompiers, soit deux phases de travail identiques entrecoupées d’une période de récupération passive courte versus prolongée.
Les résultats principaux de cette thèse montrent qu’une proportion importante de pompiers (Chapitre 2) et pompières (Chapitre 3) du Québec sont à risque moyen/élevé de MCV. Ils montrent aussi que les pompiers qui font du conditionnement physique pendant les heures de travail pratiquent plus d’activité physique par semaine et présentent de meilleurs indicateurs de santé cardiovasculaire que les pompiers qui n’en font pas (Chapitre 4). Finalement, les résultats montrent qu’une période de récupération passive d’une durée de 5 minutes entre deux phases de travail de 25 minutes lors d’une simulation d’intervention engendre une contrainte cardiaque largement plus importante qu’une période de 20 minutes et que cette différence semble être principalement redevable à une contrainte thermique et une déshydratation plus importantes (Chapitre 5).
Ces projets de recherche ont été subventionnés par les Fonds de recherche du Québec – Santé sous la forme d'une bourse d'étude de formation de doctorat. / Accounting for 43% of deaths reported in the past decade, sudden cardiac death is the most common cause of on-duty deaths among US firefighters. Studies show that the risk of on-duty cardiac events in firefighters is accentuated by two main causes: the first is the presence of coronary heart disease, cardiomegaly/left ventricular hypertrophy (LVH) and/or damage caused previously by a myocardial infarction, the second being the important cardiovascular strain suffered at work.
No studies have been conducted to assess the cardiovascular health status of Québec firefighters. Such a study would allow us to know more about their risk of cardiovascular diseases (CVD) and on-duty cardiac events. Futhermore, the prevalence of CVD risk factors was shown to be high among US firefighters, consistent with the high number of on-duty cardiac events. The first objective of this thesis was thus to assess the cardiovascular health profile of Québec male and female firefighters.
Second, in order to reduce the risk of on-duty cardiac events, it was relevant to pore over the prevention of CVD in firefighters. The risk of developing coronary heart disease and/or cardiomegaly/LVH could be reduced by engaging in and maintaining healthy lifestyle behavior including regular physical activity. Several fire departments in Québec allow firefighters to do on-duty physical training in fire stations. This could help increase their weekly physical activity level and improve their cardiovascular health. The second objective of this thesis was to compare the weekly physical activity level and various cardiovascular health indicators in firefighters who physically train on duty in the fire station and those who do not.
Lastly, in order to reduce the risk of on-duty cardiac events, it was also relevant to look at the prevention of cardiovascular strain suffered by firefighters, considering that it acts as a "trigger". This could be reduced by avoiding shortened recovery periods between periods of work during interventions. The third objective of this thesis was to compare and characterize the cardiac strain generated by two firefighting simulations consisting of two identical work bouts intercalated with a short vs. extended passive recovery period.
iv
The main results of this thesis show that a high proportion of Québec male and female firefighters are at moderate to high risk of CVD. They also show that firefighters who physically train on duty in fire stations have a higher weekly physical activity level and have better cardiovascular health indicators compared to firefighters who do not. Finally, the results show that a passive recovery period of 5 minutes between two 25-minute work bouts during a firefighting simulation results in a greater cardiac strain than a 20-minute recovery period and that this difference seems to be mainly due to a greater thermal strain and dehydration.
These projects were funded by Fonds de recherche du Québec – Santé in the form of a doctoral research scholarship.
