From left to right: increased intake of fibrous foods ie plant-derived sources such as fruits, vegetables, grains, legumes, nuts, and seeds in addition to the increased frequency of aerobic exercise patterns can increase the colonic colonization of specific bacteria ie Clostridia, Roseburia, Lachnospiraceae, and Erysipelotrichaceae. In turn, these bacteria produce anti-inflammatory byproducts ie butyrate, acetate, and propionate which are blocked due to the presence of hydrogen sulfide secondary to sulfurous amino acid fermentation.

Redwood, MD; Michael S. Marber, MBBS, PhD Background—The mechanisms of reduced angina on second exertion in patients with coronary arterial disease, also known as the warm-up angina phenomenon, are poorly understood. Adaptations within the coronary and systemic circulations have been suggested but never demonstrated in vivo. In this study we measured central and coronary hemodynamics during serial exercise. During cardiac catheterization via radial access, they performed 2 consecutive exertions Ex1, Ex2 using a supine cycle ergometer.

Throughout exertions, distal coronary pressure and flow velocity were recorded in the culprit vessel using a dual sensor wire while central aortic pressure was recorded using a second wire.

Coronary stenosis resistance was unchanged. Conclusions—On repeat exercise in patients with effort angina, synergistic changes in the systemic and coronary circulations combine to improve vascular—ventricular coupling and enhance myocardial perfusion, thereby potentially contributing to the warm-up angina phenomenon.

Thus, the phenomenon of warm-up tal setting, the salient observation is that at the accumulated angina was an enigma that attracted the attention of early external work causing maximum ST-segment depression and pioneers of physiological investigation in the cardiac cathe- chest pain on first exercise, on second exercise there is less terization laboratory.

The time of toms, previous myocardial infarction, coronary artery bypass surgery onset of ECG changes signifying exercise test positivity and the impaired left ventricular LV function, severe comorbidities, paced corresponding heart rate-central systolic blood pressure product rhythm or bundle-branch block on ECG, or inability to undertake RPP were noted.

Patients with left main stem stenoses, severe multivessel Central arterial pressure waveforms were obtained from the coronary disease, chronic total occlusions, or significant visible pressure sensor-tipped guide wire positioned in the aortic root.

Timing of the reflected pressure wave TR was attached to the catheter laboratory table. Patients were catheterized determined as the time between the foot of the pressure wave TF via the right radial artery using a standard 6F arterial sheath. Intracoronary nitrates were not used.

At this point, the guide was disengaged and the pressure Wave intensity represents the rate of energy per unit area wire was passed into the aortic root and a stable pressure signal transported by traveling waves in arteries and is derived from phasic obtained.

All signals were sampled at Hz and stored on disk for changes in local pressure and flow velocity. The study was powered to ensure there were a sufficient number of patients to observe a robust warm-up effect on second, compared with first, exertion. This was required as a firm foundation from which to observe associated hemodynamic change. The calculation was based on paired t tests within subjects, using an anticipated difference of 50 seconds for time to 1 mm STD between Ex1 compared with Ex2, with a standard deviation of 27, based on previous research.

We felt it necessary to achieve at least this level of power because it was likely multiple hemodynamic variables contributed to the warm-up effect, and their variance was possibly greater than that of the ST-segment.

Paired Student t tests were used as indicated. Repeated measures analysis of variance ANOVA with 2 within-subject factors exercise and time were used to compare the common time points between exercise exertions and evaluate the main time trends across exercise periods IBM SPSS Statistics, Version If the overall test for the main effect of exercise exertion reached significance in the ANOVA, we evaluated each separate time point with paired t tests.

We did not apply any correction for multiple comparisons, to reduce the chance of missing significant associations in this exploratory study Type II error. Mauchly test of sphericity was used to confirm the sphericity assumption. Relation- ships between variables were investigated with the Pearson correla- tion coefficient.
