Furthermore, in a prespecified analysis involving patients with a qualifying medical diagnosis of myocardial infarction, vorapaxar reduced the relative threat of the primary end stage by 20 percent. In the biggest previous placebo-controlled trial of antiplatelet therapy for secondary avoidance in patients with steady atherothrombosis or at risky for vascular disease, clopidogrel plus aspirin was no better than aspirin alone in the entire cohort.4 Nevertheless, within an exploratory analysis involving 3846 patients with previous myocardial infarction in that trial, the addition of clopidogrel reduced the risk of cardiovascular death, myocardial infarction, or stroke by 23 percent.15 Our trial involving a substantially larger number of patients with a brief history of myocardial infarction demonstrates the addition of another antiplatelet agent to aspirin therapy over the long term can achieve further reductions in recurrent atherothrombotic events in this population.Contact with ozone, an element of smog, can irritate the lung area and worsen allergy and asthma symptoms. Warmer temperatures improve the chemical reactions that type ozone also, and studies claim that climate change could boost ozone concentrations also, the NRDC says. The brand new record found that there were 275 U.S. Counties that got at least one day of unhealthy ozone conditions, and got ragweed in the area. The NRDC’s search positions also took into account details from the Asthma and Allergy Basis of America and the American Lung Association. Collectively, the ragweed pollen and ozone can interact to worsen respiratory health, making these areas especially vulnerable to a climate change-related rise in allergic and respiratory disease, the report says. Dr. Rohit Katial, program director of allergy and immunology at National Jewish Wellness in Denver, who was not associated with the record, agreed that the mix of high ozone levels and ragweed can make allergy symptoms worse than can either factor alone.
