Researchers based at the London School of Economics, Harvard Pilgrim Health Care Institute at Harvard Medical School and Stanford University School of Medicine set out to compare the effectiveness of exercise versus drugs on mortality across four conditions (secondary prevention of coronary heart disease, rehabilitation of stroke, treatment of heart failure and prevention of diabetes).
Secondary prevention refers to treating patients with existing disease before it causes significant illness.
They analysed the results of 305 randomised controlled trials involving 339,274 individuals and found no statistically detectable differences between exercise and drug interventions for secondary prevention of heart disease and prevention of diabetes.
Among stroke patients, exercise was more effective than drug treatment, while for heart failure, diuretic drugs were more effective than exercise and all other types of drug treatment.
