lifeline systems. oh, my goodness. what about what s happening at the emergency management office. what kind of preparations are you guys making and, of course, the kinds of calls you re getting? right. so i m here at our headquarters, which is also our 911 center. i just spoke to the operations floor at 911. right now we re in green status. things are good. so what we ve been experiencing are a lot of people calling 911 during these big storm events, and it overwhelms our system. so we have to do a lot of public information of let people know who to call when. we have a 311 system here in san francisco that can handle a lot of nonemergency calls like flooded roads or power outages and that sort of thing. so we encourage people to use alternate methods to 911 because people continue to have heart attacks and strokes and babies during storms, and we need to keep that line open for our life

DALLAS, Jan. 14, 2021 The longer the time between when heart attack symptoms start and a patient has an artery-clearing percutaneous coronary intervention (PCI), the more damage to the heart muscle, according to new research published today in
Circulation: Cardiovascular Interventions, an American Heart Association journal.
A heart attack happens about every 40 seconds in the U.S., and the most common heart attack is caused by a complete blockage in a coronary artery, called ST-elevation myocardial infarction (STEMI). STEMI patients are most often treated with PCI, also known as angioplasty with stent, in which a catheter with a deflated balloon is inserted into the narrowed heart artery. Subsequently, the balloon is inflated, which clears the obstruction and restores blood flow. A stent is then inserted to keep the artery open.
