Amazonian Tribe Sheds Light On Causes Of Heart Disease In Developed Countries “Chronic inflammation, which may lead to damage of the arteries, is prevalent among the Tsimane. According to the study, the Tsimane also have unusually high levels of C-reactive protein, increasingly used in clinical settings to evaluate risk for cardiovascular disease. Yet, despite these risk factors for heart attacks, the researchers found that the high levels of C-reactive protein were unrelated to risk of peripheral arterial disease (the hardening of plaque in the arteries). In fact, peripheral arterial disease "increases with age in every investigated population except the Tsimane," according to the study. Among the Tsimane, not a single adult showed evidence for peripheral arterial disease (measured using the ankle-brachial blood pressure index).”

Angina and gastroesophageal reflux diseases linked “It is well known that non-cardiac chest pain is closely related to gastro-oesophageal reflux diseases (GORD). Chest pain of oesophageal origin can be difficult to distinguish from that caused by cardiac ischaemia because the distal oesophagus and the heart share a common afferent vagal supply, and GORD can cause episodes of non-cardiac chest pain that resemble ischaemic cardiac pain. … The study results suggest that an extra-oesophageal condition causes GORD symptoms and that angina may be misclassified as GORD. Since patients with GORD have an increased risk of angina pectoris in the year after GORD diagnosis, physicians have to be concerned about missing clinically important CAD while evaluating patients for GORD symptoms.”

High Resting Heart Rate Spells Trouble for Women “Heart rate doesn't seem to matter in younger women, she said. But a higher heart rate in a woman over 50 would indicate a need for the recommended lifestyle modifications needed to prevent cardiovascular problems -- a low-fat diet, lower blood pressure, avoiding obesity and more physical activity, Hsia said. Physical activity is the key element in prevention for these women, said Dr. Suzanne Steinbaum, director of women and heart disease at Lenox Hill Hospital in New York City. "It's the same as in an athlete who is well-conditioned," Steinbaum said. "When you exercise, you increase the tone of the autonomic nervous system, which causes a decrease in heart rate and a decrease in blood pressure." The autonomic nervous system controls such basic body functions as blood pressure and digestion. "Exercise is the most potent medication we have for improving autonomic function," Steinbaum said. "If we say that exercise is essential, we know why a lower resting heart rate leads to a better outcome."”

[Inflammation and C-reactive protein in cardiovascular disease.] (Tidsskr Nor Laegeforen. 2009) “INTERPRETATION: Individuals with chronic inflammatory disease and those with high risk and acute infection are at risk for cardiovascular events and should be evaluated for primary prevention. In patient groups at moderate risk for cardiovascular disease, hs-CRP can be a valuable supplement to established factors for risk stratification. Despite numerous studies confirming hs-CRP's role as an independent risk marker, hs-CRP has not found its place in international guidelines. This should be reconsidered on the background of new study results.”

(Clin Exp Med. 2009) “Overweight and/or obesity, dyslipidemia, hypertension, insulin resistance and elevated high-sensitive C-reactive protein are seen in patients with skin tags. Skin tags may be a marker of increased risk of atherosclerosis and cardiovascular disease.”
