Book Description
Patients with heart failure (HF) suffer from symptoms such as dyspnea, fatigue and reduced quality of life, which affect their physical function and often lead to immobilization and poor survival prognosis. Exercise training in cardiac rehabilitation should be offered to every patient with HF and can be performed both in a hospital-setting and with a home training programme. Exercise, in patients with HF, improves physical function and functional capacity as well as health-related quality of life (HRQoL) and reduces the need for hospital care. There are several barriers against participating in exercise based cardiac rehabilitation despite information about its benefits. The patient may anticipate not being able to exercise, that the exercise would be too hard, lives far away or has not been referred. Aim: The aim of this thesis was to evaluate the effects of exercise in heart failure patients, of a one-year training programme, with hospital-based training followed by a home-based setting or only home-based, with special emphasis on peripheral muscle training (PMT). Furthermore, to study frequently used methods for evaluation of the effects, i.e the 6-minute walk test and instruments for estimating health-related quality of life. Methods and findings: In study I, PMT was evaluated and the PMT programme in a hospital-setting (with equipment) and subsequent homebased training (with elastic bands) was compared with solely home-based training, over 1 year. At follow-up every third month, duplicated six minute walk test (6MWT) and two HRQoL questionnaires were used. The walking distance increased significantly after three months in both groups and was maintained thereafter. Also HRQoL increased but at different time points. In study II, PMT was compared with interval training on an ergometer bike/free walking. Both groups started under supervision of a physiotherapist in a hospital-setting, for three months and thereafter at home for nine months. The same measurements were used as in study I. Neither walking distance nor HRQoL changed over the study period. However, this may be regarded as a positive effect in the light of the known progressive nature of heart failure. In study III, the 6MWTs from study I and II were used to evaluate the necessity of performing duplicated 6MWTs in follow-ups clinically and for research purposes. We found that it is sufficient to perform one 6MWT. In study IV, both 6MWT and HRQoL forms from study I and II were used to investigate the relationship between walking distance and perceived HRQoL in HF patients. Patients with shorter walking distance, than the group median, experienced poorer general HRQoL but not HRQoL related to HF, than the higher performing half of the study group. There were no longitudinal trends in these relationships. Conclusion: PMT can be used as an exercise modality in patients with HF, both in hospital and at home, and may be evaluated with a single 6MWT. Shorter walking distance was related to a lower general HRQoL as judged by the patients but there was no significant relation between short walking distance and the HF-related HRQoL. Individualizing the training programme and methods, and offering the choice of exercise modality and the possibility of exercising at home, might be a way to increase adherence in cardiac rehabilitation. Patienter med hjärtsvikt besväras av andfåddhet och trötthet vilket påverkar deras fysiska funktion och ofta leder till immobilisering, nedsatt livskvalitet och dålig prognos. Träning inom hjärtrehabilitering bör erbjudas alla patienter med hjärtsvikt och kan utföras såväl på sjukhus som hemma med hemträningsprogram. Träning vid hjärtsvikt förbättrar fysisk funktion och funktionell kapacitet, hälsorelaterad livskvalitet, och minskar behovet av vård på sjukhus. Det finns många barriärer till att delta i hjärtrehabilitering trots information om vinster, t ex att patienten tror sig inte klara av att träna, bor långt ifrån, har inte fått remiss för att nämna några. Syfte: Syftet med avhandlingen var att utvärdera effekterna av ett träningsprogram för patienter med hjärtsvikt under 1 år, träning på sjukhus följt av hemträning eller enbart hemträning. Ett specifikt syfte var att utvärdera perifer muskelträning (PMT) som en möjlig, lämplig träningsmetod för hjärtsviktspatienter. Vidare var syftet att utvärdera effekten av sex minuters gångtest och hälsorelaterad livskvalitet. Metod och resultat: I studie I utvärderades PMT och jämförde träning på sjukhus (med redskap) med efterföljande hemträning (med elastiska band) med enbart hemträning under 1 år. Vid utvärdering var tredje månad användes dubbla sex minuters gångtest och frågeformulär om livskvalitet. Gångsträckan ökade signifikant efter träning och höll i sig hela träningsperioden i båda grupperna. Även livskvaliteten ökade men vid olika tidpunkter. I studie II, jämfördes PMT med intervallträning på ergometercykel/promenader. Båda grupperna tränade under ledning av fysioterapeut i tre månader och därefter hemma upp till 1 år. Samma utvärdering som i studie I. Gångsträcka och livskvaliteten ändrade sig inte under studietiden. Det kan dock ses som en positiv effekt eftersom hjärtsviktspatienter vanligen försämras över tid. I studie III, användes gångtesten från studie I och II för att utvärdera om det är nödvändighet att utföra dubbla sex minuters gångtest vid utvärdering. Ingen kliniskt betydelsefull skillnad sågs mellan gångtest ett och två. I studie IV, användes både gångtest och livskvalitetsformulär, från studie I och II, för att undersöka samband mellan gångsträcka och upplevd livskvalitet och om detta samband ändrades med tiden. Patienter med kortare gångsträcka upplevde sämre allmän hälsorelaterad livskvalitet men inte livskvalitet relaterad till hjärtsvikten, någon kliniskt signifikant förändring över tid kunde inte påvisas. Konklusion: Perifer muskelträning kan användas som en säker träningsform för patienter med hjärtsvikt, både på sjukhus och som hemträning och kan utvärderas med endast ett sex minuters gångtest. Patienter med kortare gångsträcka upplever sämre allmän livskvalitet vilket förefaller relativt oberoende av de olika testtidpunkterna.

Book Description
Exercise testing has become an integral component of the management of patients with chronic heart failure. Exercise and heart failure can be seen to have a dynamic interrelationship, in which exercise can provide important diagnostic information, yet can also be used to assess the effectiveness of treatment regimes, and as a therapeutic intervention in itself. This is the first book that directly and comprehensively addresses the issues involving exercise patients with heart failure and heart transplants. It presents a unique and comprehensive overview of epidemiological, physiological and clinical aspects of this relationship. The text covers the physiology of myocardial dysfunction, the transplanted heart, and ventricular assist devices as they affect exercise capacity and responses during exercise and exertion. It goes on to discuss in more depth the exercise testing of patients, including the methods and utility of ventilatory gas analysis, the physiologic and clinical effects of exercise training on these patients, and ecommended exercise training programs This text, part of the American Heart Association Monograph Series, provides a cogent and comprehensive overview of its topic that should be of practical value to a broad range of physicians, exercise physiologists and consultants working in this field.

Book Description
This study on "Exercise testing and training in coronary heart disease" is a remarkable compilation of numerous research studies, primarily from labora tories in Europe and the United States over the last decade or more. The topic reflects a growing awareness of and concern about the rapidly expanding understanding of the pathophysiology of coronary atherosclerotic heart disease. Since muscular exercise increases aerobic metabolism of myocardial and working skeletal muscles, greater flow of oxygenated blood is required by each; yet underlying vascular disease restricts these responses. This implicit paradox is here considered forthrightly. Examination of these relationships in symptomatic patients requires care and caution, because of the potential and occasionally real risks entailed. Accordingly, indirect assessment, particularly by noninvasive techniques, becomes increasingly important to detecting and monitoring - for the safety of the patients studied - the evidence of myocardial ischemia and impairment of left ventricular function under stress. Adequate assessment requires well-designed experimental studies to quantify true relationships and to measure the limits of functional capacity and the mechanisms of its impairment. Further more, alterations can be induced by therapy, whether this be pharmacological, medical or surgical, or achieved by physical reconditioning through exercise training. Not only is the cardiovascular system impaired by discrete and diffuse vascular lesions at central sites, but the degree of impairment is dynamic rather than static.

Book Description
Cardiovascular, respiratory, and related conditions cause more than 40 percent of all deaths globally, and their substantial burden is rising, particularly in low- and middle-income countries (LMICs). Their burden extends well beyond health effects to include significant economic and societal consequences. Most of these conditions are related, share risk factors, and have common control measures at the clinical, population, and policy levels. Lives can be extended and improved when these diseases are prevented, detected, and managed. This volume summarizes current knowledge and presents evidence-based interventions that are effective, cost-effective, and scalable in LMICs.
