Coffee does not increase severity of coronary artery disease

Coffee consumption does not affect the severity of coronary artery disease (CAD), reveals a study by the Inter Graduate in Applied Human Nutrition (PRONUT) USP. The study of Juliana Gimenez Casagrande nutritionist in 115 patients with CAD shows an increase of 50 ml in daily intake of the drink, equivalent to a cup volume may decrease by about 3.15% probability the patient came to provide a framework more severe disease.
The research analysed patients from the outpatient cardiology InCor Osasco, Polyclinic located in North Zone Dona Leonil Crê Bortolosso in Osasco (São Paulo) and the Clinical Unit of Chronic Coronary Heart Institute (Incor), Hospital das Clinicas (HC) Faculty of Medicine, USP (USP). "The selection criteria used for inclusion of patients with coronary disease were diagnosed history of CABG, angioplasty and coronary angiography examination finds that coronary obstruction", says nutritionist.
According to Juliana Casagrande, few studies show any meaningful conclusion about the effects of coffee consumption on heart disease. "Most studies the effect on risk factors for CHD, such as dyslipidaemia (elevated levels of lipids in the blood), diabetes mellitus and hypertension", points. "Survey participants received no specific guidance on the amount of coffee to be consumed, only those who drank moderately were instructed to drink that there was no need to completely stop eating."
Patients were followed for a year and a half. The clinical status of patients was assessed through a questionnaire with about 25 questions divided into six sections: identification, classification, socio-economic, medical history, anthropometric, dietary habits (including coffee consumption) and quality of life. The study showed that coffee intake showed a significant relationship with lower levels of severity of CAD. "There were no ill effects to the quality of life of people with the disease," says Juliana Casagrande. "The only significant inverse relationship was between coffee consumption and stable angina (chest pain of cardiac origin)."
The researcher says that research has not determined a specific amount of consumption of coffee that is good or bad for the DAC. "What has been observed is that increasing the daily intake of 1 ml of coffee in approximately 0.063% decreases the likelihood of the patient come to present a worse picture of the disease," he explains. "Converting in proportions greater, increasing the daily intake of 50 ml of coffee decreases by about 3.15% probability the patient come to present a more severe CAD". The dietician who reported other studies have hypothesized that the presence of antioxidants in the drink is associated with a reduction in inflammatory processes that trigger DAC.
The study also found a relationship between fat consumption striking, severity of CAD and physical ability. "Many studies already suggest a beneficial relationship between coffee consumption with yet undetermined amount, and risk factors for the disease," says nutritionist. "A relationship that should still be viewed with caution is excessive consumption in patients with hypertension, as has been seen that a moderate intake of drink does not elevate blood pressure."
The nutritionist indicates that coffee consumption should not be prohibited for patients with CAD. "Many health professionals recommend a total restriction," he says. "However, although research has not been conclusive about the ideal amount, the more suitable it is suggested moderate consumption, which is calculated in 3-5 cups per day. The display also varies according to the presence or absence of hypertension in the patient."
