The patients were between 50 - 65 years of age presenting with anterior, lateral, and inferior STEMI (ST-Elevation Myocardial Infarction). Seven of the patients were female, and 14 were male. They presented to an emergency room of a rural hospital that did not provide emergency percutaneous coronary angioplasty/stenting (PTCA/stenting). The hospital is about 70 minutes from a facility that provided PTCA/ stenting—all the patients presented with typical angina chest pain with ST elevation. They are hemodynamic stable. Most patients received Lopressor 35 mg IVP, with one receiving 115 mg in a 5 mg increment. They were chest pain-free and hemodynamically before leaving the ER for the transfer for PTCA/stent. The results demonstrated that beta-blockers are effective in relieving pain in STEMI patients. Further study is needed to determine its efficacy, safety, and how to use it.展开更多

In the 20+ years, 64 patients were treated, including both with reduced and preserved left ventricular function. Most patients had a 4 - 5 days hospitalization in their first admission with one readmission (1.6%) over seven years. This paper will help us understand the physiology and pathophysiology of congestive heart failure, especially how to use beta blockers and diuretics. It will shorten the length of hospitalization and lower the readmission rate and cost of CHF treatment. This paper will help us to open another research direction for CHF.展开更多
