Advancing beyond the "heart-healthy diet" for peripheral arterial disease.

ABSTRACT: Peripheral arterial disease (PAD) is a burdensome cardiovascular condition that results from chronic inflammatory insults to the arterial vasculature. Key risk factors include age, gender, type 2 diabetes mellitus, hypertension, hypercholesterolemia, hyperhomocysteinemia, smoking, lack of physical fitness, and poor diet, the latter three being modifiable in the development and progression of PAD. A growing body of evidence indicates that imbalanced nutrient intake may contribute to the development and progression of PAD. The purpose of this review is to summarize current knowledge about nutritional patterns among patients with PAD and to ascertain whether certain health-promoting foods and nutrients could benefit patients with this condition.We conducted a comprehensive literature review to examine primary source evidence for or against the nutrients that are commonly associated with PAD and their potential utility as therapies.We summarized nine categories of nutrients, as well as four diets endorsed by the American Heart Association that may be prescribed to patients with or at risk for PAD. The nutrients reviewed included omega-3 polyunsaturated fatty acids (n-3 PUFAs), folate and B-series vitamins, and antioxidants. The diet plans described include the Dietary Approaches to Stop Hypertension (DASH) diet, Mediterranean diet, low-fat diet, low carbohydrate diet, Dr Dean Ornish's Spectrum Diet and Dr Andrew Weil's Anti-Inflammatory Diet.PAD is a chronic inflammatory condition that is associated with longstanding poor nutrition habits. We advocate for an intensified use of diet in PAD therapy, and we specifically recommend following eating patterns that are rich in nutrients with anti-inflammatory and antioxidant properties.

Project description:Background and purposeNovel noninvasive measures of vascular function are emerging as subclinical markers for cardiovascular disease (CVD) and may be useful to predict CVD events. The purpose of our prospective study was to assess associations between digital peripheral arterial tonometry (PAT) measures and first-onset major CVD events in a sample of FHS (Framingham Heart Study) participants.MethodsUsing a fingertip PAT device, we assessed pulse amplitude in Framingham Offspring and Third Generation participants (n=3865; mean age, 55±14 years; 52% women) at baseline and in 30-second intervals for 4 minutes during reactive hyperemia. The PAT ratio (relative hyperemia index) was calculated as the post-to-pre occlusion pulse signal ratio in the occluded arm, relative to the same ratio in the control (nonoccluded) arm, and corrected for baseline vascular tone. Baseline pulse amplitude and PAT ratio during hyperemia are measures of pressure pulsatility and microvascular function in the finger, respectively. We used Cox proportional hazards regression to relate PAT measures in the fingertip to incident CVD events.ResultsDuring follow-up (median, 9.2 years; range, 0.04–10.0 years), 270 participants (7%) experienced new-onset CVD events (n=270). In multivariable models adjusted for cardiovascular risk factors, baseline pulse amplitude (hazard ratio [HR] per 1 SD, 1.04 [95% CI, 0.90–1.21]; P=0.57) and PAT ratio (HR, 0.95 [95% CI, 0.84–1.08]; P=0.43) were not significantly related to incident composite CVD events, including myocardial infarction or heart failure. However, higher PAT ratio (HR, 0.76 [95% CI, 0.61–0.94]; P=0.013), but not baseline pulse amplitude (HR, 1.15 [95% CI, 0.89–1.49]; P=0.29), was related to lower risk for incident stroke. In a sensitivity analysis by stroke subtype, higher PAT ratio was related to lower risk of incident ischemic stroke events (HR, 0.68 [95% CI, 0.53–0.86]; P=0.001).ConclusionsNovel digital PAT measures may represent a marker of stroke risk in the community.
