A study determines an inverse link between the level of supine systolic blood pressure gauged on admission to an intensive care unit for severe chest pain and danger of death at one year. Those patients with high systolic blood pressure seem to encompass an improved prognosis following a year.
High blood pressured when gauged post a resting duration is said to be among the best investigated and corroborated threat issues for cardiovascular disease.
The authors commented, “However, little is known about the relationship between BP under acute stress, such as in acute chest pain, and subsequent mortality.”
Fredrik H. Nystrom, M.D., Ph.D., and colleagues from Linkoping University, Linkoping, Sweden, evaluated the death rate in association with supine systolic BP gauged at admission to an intensive care unit (ICU) for chest pain during 1997 till 2007. The study comprised of assessment of data from roughly 1,19,151 patients in a registry that integrates all Swedish hospitals. Outcomes from this study were offered as per systolic BP quartiles like Q1, less than 128 mm Hg, Q2 from 128 to 144 mm Hg, Q3, from 145 to 162 mm Hg, and Q4, at or more than 163 mm Hg. It was seen that the average follow-up was roughly 2.5 years.
The study authors discovered that the one-year mortality rate, following adjustment for several issues appeared to illustrate that participants in Q1 of systolic BP seemed to encompass greatest threat for death. On the other hand, patients in Q4 seemed to have the best prognosis.
The authors quoted, “Corresponding adjusted absolute risks were a 21.7 percent lower absolute risk for death within 1 year for patients in Q4 compared with Q2. The mortality risk was 15.2 percent lower for patients in Q3 compared with Q2 while the risk for patients in Q1 was 40.3 percent higher for mortality compared with that in Q2.”
The authors remarked, “High supine systolic BP measured in patients with acute chest pain was associated with a favorable 1-year prognosis. There is an inverse association between admission supine systolic BP and 1-year mortality rate in patients admitted to the medical ICU for chest pain.”
The authors mentioned that this finding also applies to those patients who are diagnosed with ischemic heart disease and those who eventually develop heart attack.
The study is published in JAMA.
