Red cell and platelet distribution widths in patients with angina pectoris and acute myocardial infarction

Abstract

Aim: We aimed to determine the relationship of red cell and platelet distribution widths with the onset of acute myocardial infarction, to enable the early detection and prevention of acute myocardial infarction.Methods: Red cell and platelet distribution widths were retrospectively determined in 46 patients with stable angina pectoris and 140 patients with acute myocardial infarction who were brought to the emergency department of our institution. Red cell and platelet distribution widths were determined with an automatic blood cell analyzer, and the results were compared between the acute myocardial infarction and angina pectoris groups.Results: Both red cell and platelet distribution width values obtained at onset were significantly higher in the acute myocardial infarction group than in the angina pectoris group (red cell distribution widths, 46.4 AE 0.51% versus 44.5 AE 0.59%; mean difference À1.91 [95% confidence interval (CI), À3.79 to À0.34]; platelet distribution widths, 12.1 AE 0.22 fL versus 11.1 AE 0.17 fL; mean difference À1.03 [95% CI, À1.58 to À0.47]). The red cell distribution widths before onset was not different between the acute myocardial infarction and angina pectoris groups; however, the platelet distribution widths before onset was higher in the acute myocardial infarction group (red cell distribution widths, 46.5 AE 0.85% versus 45.9 AE 0.59%; mean difference À0.71 [95% CI, À2.74 to 1.30]; platelet distribution widths, 11.4 AE 0.39 fL versus 10.6 AE 0.21 fL; mean difference À0.83 [95% CI, À1.66 to 0.11]). Conclusion:Red cell distribution widths and especially platelet distribution widths may contribute to the early detection of acute myocardial infarction.

Correlation between neutrophil to lymphocyte ratio (NLR) and red cell distribution width to platelet ratio with ST segment resolution and 2 month complications in patients with acute myocardial infarction undergoing primary coronary intervention

“…Our study revealed that among 211 patients, 181 of them (85.8%) were male and 30 of them (14.2%) were female which is accordance with the results of other studies which report that acute myocardial infarction happens more in men compared to women (16)(17)(18)(19)(20)(21)(22).…”

“…In Gul et al study the age average was 56±13 (18). In another study conducted in Japan the age average was reported to be 66±1 (19). in most performed studies, acute myocardial infarction happened in 60s in majority of patients (20)(21)(22).…”

“…In a study performed in Japan it was concluded that RDW and PDW was significantly higher in patients with acute myocardial infarction (19). In this study they investigated the difference of these 2 indexes between patients with angina pectoralis and myocardial infarction.…”

Clinical Treatment Analysis and Imaging Study of Patients with Acute Angina in Cardiovascular Medicine

“…The main types of pain are burning pain, squeezing pain, and clamping pain. The duration of pain in patients is generally 3 to 5 minutes, and there is short-term pain within 1 minute [ 18 ]. If the pain is relieved after taking nitroglycerin, it can be diagnosed.…”
