The congenital heart disease

The congenital soft nervusedness diseaseDoes an deterrent example Program following cardiac Surgery for essential Heart Defects improve a Childs Cardiopulmonary Response to dress and Increase Exercise Tolerance?IntroductionPaediatric Cardiac Problems be prevalent throughout the world with 1.5 m disturbedion new cases diagnosed each year. Congenital Heart disorder (CHD) is the most common diagnosis of heart riddles at abide. Between four and nine per unity thousand springy births each year be diagnosed with the condition (Draper 2008). In 2007, 989 live births were recorded of babies with cardiovascular abnormalities (National Statistics 2007). Congenital Heart Disease is an umbrella line which encompasses all heart defects that are present when a child is born. The child may have one or multiple defects at birth which can all be detected by a scan ante-natally or are diagnosed soon after birth. Although the diagnosis of CHD is now get easier, some diagnoses of the cond ition do non happen till later on in life. Statistics utter that approximately 60% of congenital heart disease are diagnosed in babies aged from birth to one year, 30% in children aged one to fifteen, and 10% in adulthood (16 years and over) (BHF 2003). M whatsoever common conditions include a Ventricular septate Defect (VSD), an Atrial Septal Defect (ASD), Pulmonary Artery Stenosis, Tetralogy of Fallot (TOF) (Fig. 1) and Transposition of the Great Arteries (TGA) (Fig. 2).Congenital Heart Disease is now not just a problem of the child, many people with the condition are now living into adulthood. It is predicted that by 2010, 185,000 people will be living in the UK with CHD (Deanfield (BHF) 2003). Treatment for Congenital Heart Conditions has changed rapidly over the last 50 years. Now surgical management is needed in most cases however some defects will either resolve themselves or require medication. Surgical treatment has changed in recent judgment of convictions, fewer patie nts are requiring open heart mental process and more(prenominal) are receiving a catheterisation technique. Around 3,100 operations and 725 interventional cardiac catheterisations are performed each year on babies and children with CHD (BHF 2003).The effects of surgical interventions on cardiorespiratory function have been thoroughly researched in the past. The studies have concluded that surgery does improve lung and cardiac function and reduces secondary complications (Picchio 2006).Exercise is widely known as the best treatment for most musculoskeletal problems moreover its effects on the cardiopulmonary system has totally recently been researched into (Cullen 1991). Pulmonary and Cardiac Rehabilitation have now been shown to have an effect in adults scarcely the research into paediatric rehabilitation classes is not widely known about.Other studies have looking ated at object lesson training or a cardiac rehabilitation create by mental acts following surgery and the e ffect of this on the patients manipulation tolerance. I am going to use this review to assess these studies which look at twain cardiac rehabilitation programmes and amyotrophic lateral sclerosiso levels of exercise tolerance following surgery. I want to discuss whether there are any gaps in the knowledge prow surrounding the effects of exercise in cardiac surgery of paediatrics. I likewise want to conclude whether the assumption that exercise is compulsory, can be in good order justified.MethodAfter deciding a topic I was up to(p) to start researching into the background area of paediatric cardiology. I started by using a combination of terms including, Exercise, Sports, Physical Activity, Paediatrics, Children, Post-Cardiac Surgery, Congenital Heart Disease, Congenital Heart Defects and Cardiac Rehabilitation. The search pages I found highlighted articles of relevance and then I apply the link to related articles to find the studies ( reassure appendix 1). I also searched o n individual journal websites including, Paediatric Cardiology and Cardiology in the Young. I used databases such as Pubmed, Medline, Ovid, Sciencedirect and Springerlink to read abstracts of articles and decide their relevance to my review. I then selected the most relevant and used excel to compile a table where I could easily see the differences in the studies under headings (see appendix 4).The studies I am looking at are all based on paediatrics and are randomised controlled trials go out from 1981 to 2009. Although some of the studies are nearly thirty years old, they hold some strong evidence compared to present day studies and therefore I have not discounted older studies from this review.Other reviews have assessed whether exercise has an impact on cardiopulmonary performance and have been shown that an exercise rehabilitation class does provide benefits in cardiopulmonary performance and exercise capacity. Some of the studies that are being reviewed however are concluding with insignificant findings. The reviews have stated that research lacks bulky-term effects of training and also a clear earning as to which exercise type is best (Tomassoni 1996). In this review I will try look at newer studies and see if the areas of knowledge that were found to be omitted after previous reviews have now been researched into.Review of StudiesFirstly I am going to discuss the interrogatory of the participants. All of the studies completed two exercise tests to assess the participants ability before and after either the cardiac rehabilitation program or surgery. Exercise interrogatory is very difficult to re gravel. Many studies have problems with ensuring the test is accu prise and reliable and many struggle, causing results and testing to be distinct and therefore not comparable. If the results are not accurate and cannot be compared to other studies the results can cause a change in average results and therefore may mislead readers into a trumped-up(preno minal) positive result.Each of the studies used either a treadmill test or a cycle ergometer to test their participants cardiopulmonary function and exercise tolerance. Using these two tests is the most common technique of testing function as it is very reliable. (Washington 1994) All studies used a specific protocol outlined in the Washington Guidelines with all of the studies using a treadmill test with five of the thirteen studies using Bruces protocol. Bruces protocol is where the socio-economic class of exercise is increased any 3 minutes until the participant has reached their maximum capacity and cannot continue. The bicycle ergometer tests are where the participants are required to cycle continuously at approximately 50-60rpm where the grade of exercise is increased by 10-20 watts/ minute every three minutes. This is also completed until the participant can no farsighteder continue (Washington 1994).Exercise testing using a treadmill or a cycle ergometer causes problems because the task they are undertaking in the test are is not operative and do not relate to daily tasks. Running and cycling is functional but not to that grade of exhaustion. Many children normally will stop an exercise when they are tiring and will never push themselves to the level that these exercise tests are pushing them. The tasks are also not fun for the participants and I scent that it should be fun otherwise children will get bored. This is the same with the intervention as well and the programmes should be child orientated and individual to each child. end Measures are the basis to the results of a body of work and therefore its effectiveness. A lack of certain yield measures may show large flaws in a acquire as many can be used to assess different parts of function and physiological activities. In the studies looking at the effects of cardiovascular surgery, there were a limited number of outcome measures that were looked at. Sarubbi (2000) completely looked at hear t rate and blood pressure as outcome measures and this limits results. The main outcome measures were heart rate, blood pressure and maximum work rate in all the studies. These outcome measures although very limited are values that help us to understand cardiovascular activities. Other helpful measures would have been oxygen saturations, which only Rhodes studies (2005/6) looked into. Saturations are helpful to assess whether a change in heart rate or blood pressure affects saturations or whether a change in these may be due to a ventilation problem. (Rivers 2001)The outcome measures of the cardiac rehabilitation studies are all different but all have similarly looked at exercise capacity after the intervention. This is shown by all the studies using VO2 as a measure and that all the participants improved their VO2 maximum to allow for a greater exercise capacity. The only study that did not prove an increase in VO2 max was Goldbergs study (1981) which only showed an overture in ma ximum work rate. This could have been due to the date in which the study was undertaken. This was one of the earlier studies through in 1981 and therefore engineering science may not have been as accurate or as reliable as some of the later studies do since 2000. However Goldbergs study was the one that had the most intervention time of all the studies with exercise of up to 45 minutes completed on alternate age with a strict regime to increase grade of exercise over the 6 weeks. This leads me to believe that maybe it was inappropriate testing or inaccurate technology that changed the results of the study as previous reviews have shown that an increase in exercise time has shown to have positive effects on health. As technology has create since the early eighties, this may be why more accurate testing is used and therefore making results more positive to the outcome we wish.Another problem in trials of this sort is compliance. Compliance is always an issue when completing studie s (Burke 1997). Initially recruiting people to participate is difficult and many people with either choose not to participate or may drop-out early in the study. Many people will not participate because of exercise testing being too trespassing(a) or because of geographical implications as the distance to the base of the study being an issue. Some of the studies had large drop-out rates with almost 30% decrease in patients ab initio viable for the treatment plan and those who undertook the tests in the study (Arvidsson 2009). I think this could be explained by that the studies involved child participants that are less compliant to long term programmes and who tire easily to an activity. in like manner due to the nature of the surgery that they have all completed, many parents will be protective over their children and be pushing the participants exercise tolerance will make many parents worried about their childs health. Much of this can be avoided by specifically explaining the p rocedures and answering any questions that the parent or participant may have to educate them that this a treatment plan and is not going to hinder their childs recovery or health.Also intervention time is a major issue when looking at trials. Some may be days long and others have follow-ups of years erst the intervention has finished. The studies that focus on Cardiac rehabilitation all have various time scales of their intervention with the shortest program being six weeks (Goldberg 1981) and the longest around twenty weeks (Opocher 2005). The difference in timescale and the different number of sessions that the participants attend makes it difficult to assess whether it is the content of the program that affects the patients or whether just exercising over a longer, more sustained period of time effects the participants in the same way. I think studies that look at different contents of treatment programmes but have a fixed intervention time may be beneficial in deciding the aim of this review.When looking at the studies, all of the cardiac rehabilitation programs only assess the patients exercise performance straight after the program and only one study looks at the effects of the program long term. Rhodes et al 2005 firstly looked at the immediate effect of a cardiac rehabilitation program and then in 2006 did another study looking at the same participants of the previous study six months after the original program. The studies that look at exercise capacity before and after surgery also do not look at the effects of the cardiovascular system in response to exercise on a long term scale. Long term effects are the best indicator to say that function and exercise capacity has improved (Miller 2005).Sociodemographics of the subjects in a study are also cardinal to review as to its involvement in accuracy of results. Different age ranges or male to female ratios cause studies to be inaccurate in nerve-racking to generalise the population group. Many of the studies had a very large age range within their participant groups with the largest difference being 17.6 years in Marino et als study in 2005. I feel that the exercise difference between a seven year old is very different to that of a cardinal year old. I feel that a large age range is used to increase subject numbers. Male Female ratios are also of the essence(p) and that a large majority in these studies had male participants. The biggest ratio of male to female was in Opochers (2005) study where there were nine male participants and only one female participants. The best ratio of male female was either Moalla (2006) study with 44 males and 39 females. This is important as I believe men and women react differently to exercise.Subject numbers is also a large problem with these studies. Due to most of the studies only looking at the children that have had surgery in their trust or hospital they have decreased their subject numbers and none of the studies look at the effects on large number of subjects on a national scale. The studies that looked at cardiac rehabilitation all have subject numbers under 16 which is a very big limitation. The only studies that have larger numbers are the ones that look at exercise capacity after surgery. By having participants that are only from the immediate area of the study base also means you do not get a generalised view of everyone nationally and you may not cover different children from different backgrounds socially and economically and so may have different attitudes to rehabilitation, treatment and self-management.Studies with participants that are not generalised to their population group can therefore produce a bias result to that specific population group. Also having different backgrounds of participants is important in assessing their compliance and what individual exercise programme they should be given. Having a specific age range is particularly important as many of the subjects may be inappropriate for the programme due to their age. Some of the subjects may be too young and using subjects that are under six years old would be inappropriate due to the subjects being too young to understand the instructions of the study. Using older subjects may also cause different results as their bodies have had longer to regain independent function and the body has had time to compensate for a lack in cardiopulmonary function. I think it is important to keep variables as succinct as possible and trials should be able to based on one variable alone and truly work on whether surgery or exercise has an effect on that variable independently.personal effects of Cardiac RehabilitationThe studies looking at cardiac rehabilitation all have an exercise programme set up for their patients either at dental plate (Moalla 2006) or in an outpatient setting (Ruttenberg 1983). These sessions ranging in therapy time from one hour alternate days to one hour once a week, all show an increase in either cardiopulmona ry performance or in exercise tolerance. This shows that a rehabilitation programme is appropriate for these patients and does have a positive effect on the participants life. Rhodes studies (2005/6) had the greatest effect on the patients final outcome. Not only did most of the testing result in significant effects but the large range of outcome measures used means that we can assess not only the cardiovascular performance of the participant but also look at the pulmonary effects of the exercise and their effects of the heart and the cardiac system.What we can also see from this review is that the cardiac rehabilitation programmes are becoming more significant in results as the studies get newer. This is a good indicator that current programmes are being effective in their rehabilitation (Opocher 2005, Rhodes 2005/6, Moalla 2006) and that newer techniques and more knowledge on exercise has lead to better run classes which not only improve results more consistently than the older st udies and that the effects from an initial programme can also be maintained for 6months after intervention (Rhodes 2006).Effects of Cardiovascular SurgeryTwo of the studies looking at effects of surgery only have exercise testing after the surgery. The study by Arvidsson only used the number of sports sessions a week that the participant goes to after the surgery. Therefore a direct comparison between their before and after the surgery ability cannot be done and so the study is only looking at their sports connection after surgery and not the effects of the surgery. However these studies do show that after surgery childrens exercise tolerance increases to the level that healthy participants are achieving (Zaccara 2003) and they are move in equal amounts of sports participation following surgery (Arvidsson 2009)Future ideasIn future studies, long term effects of cardiac rehabilitation should be researched, with a follow-up test of a least a year after their rehabilitation to see if the participant is now more active. I also think a control group should be used in the study to look at the effects of non-surgical patients that also participate in cardiac rehabilitation. This is to assess whether the improvement seen during cardiac rehabilitation is not just a response to any exercise and that if a child went back to normality and participating in sports then they will just be as exercise tolerant as children who do not have CHD. Also I would counsel that an exercise programme for the patients that is more functional but also fun and exciting for the patient should be used to increase compliance and also enjoyment for the participants and their parents.ConclusionIn conclusion, Cardiac surgery is a commonly used form of reducing congenital heart defects and has been shown by these studies that the surgery does have an improvement on the patients cardiopulmonary performance. I have also found that a cardiac rehabilitation programme is beneficial for paediatric p atients after cardiac surgery for congenital heart defects.References/ BibliographyArvidsson, D (2009) Physical Activity, sports participation and aerobic fitness in children who have undergone surgery for congenital heart defects.
