Some cardiovascular diseases exacerbated by dramatic climatic change. According to experts, the age factor is crucial because, in this case, patients over 70 years with associated diseases like diabetes, hypertension and renal insufficiency are more likely to become unstable to a sudden change of weather.

Thus, seasonal variation, especially in cold weather, can influence bodily activity modifying sympathetic tone, blood viscosity, blood pressure and heart rate, which tend to increase, in turn raising the demand for oxygen the body.

With the drop in temperatures, those with cardiovascular history are more likely to suffer complications as cardiovascular diseases are mainly associated with cold. In this sense, in winter stands the prevalence of cardiovascular diseases such as ischemic heart disease, angina pectoris and acute myocardial infarction.

“This is mainly due to the cold causes a narrowing of the arteries of the body and can lead to coronary level, a decrease of the blood supply to the heart,” says Dr. Leandro Plaza Celemín, president of the Spanish Heart Foundation (FEC). Mortality and morbidity from heart disease (CHD) follows a heterogeneous geographical distribution among different countries and even within countries. In this sense, “Metabolic Syndrome (MS) is unevenly distributed geographically in the Spanish territory,” explains Dr. Montserrat León, Aragon Institute of Health Sciences. “Certain other areas are almost twice the frequency of the disease and also match those which have highest rates of CHD mortality,” he adds.

This is one of the conclusions drawn from research work conducted by Spanish specialists and coordinated by Dr. Leon. “This study is part of a broader conducted by the Working Group of Metabolic Syndrome Spanish Society of Cardiology, specifically, Section of Preventive Cardiology and Rehabilitation,” says this doctor.

According to investigators, the idea of raising this study came to the high prevalence represents the Metabolic Syndrome according to several American studies and the lack of epidemiological data of this disease in Spain. The group of specialists who participated in the work belong to different disciplines: family physicians, cardiologists, internists, and company doctors, residents, and statistical and other technicians.

The study sample consisted of workers recruited in the health examinations conducted by their companies.

“We use this group for the ease in obtaining the data from their annual medical examinations for the high prevalence of risk factors in this age and the impact they might have on prevention measures.
