Usefulness of the neutrophil to lymphocyte ratio in predicting long-term mortality in ST segment elevation myocardial infarction.
Neutrophil to lymphocyte ratio (N/L) has been associated with poor outcomes in patients who underwent cardiac angiography. Nevertheless, its role for risk stratification in acute coronary syndromes, specifically in patients with ST-segment elevation myocardial infarction (STEMI), has not been elucidated. We sought to determine the association of N/L maximum value (N/L max) with mortality in the setting of STEMI and to compare its predictive ability with total white blood cell maximum count (WBC max). We analyzed 515 consecutive patients admitted with STEMI to a single university center. White blood cells (WBC) and differential count were measured at admission and daily for the first 96 hour…
Relationship between low lymphocyte count and major cardiac events in patients with acute chest pain, a non-diagnostic electrocardiogram and normal troponin levels.
Risk stratification of patients with acute chest pain, non-diagnostic electrocardiogram and normal troponin (ACPneg) remains a challenge, partly because no standardized set of biomarkers with prognostic ability has been identified in this population. Lymphopenia has been associated with atherosclerosis progression and adverse outcomes in cardiovascular diseases; although its prognostic value in ACPneg is unknown. We sought to determine the relationship between the lymphocyte count obtained in the Emergency Department (ED) and the risk of the long-term all-cause mortality or myocardial infarction (MI) in patients with ACPneg.We analyzed 1030 consecutive patients admitted with ACPneg in our i…
Therapeutic implications of low lymphocyte count in non-ST segment elevation acute coronary syndromes
Abstract Background Low lymphocyte count (LLC), a surrogate for inflammation, has emerged as a potential risk factor for cardiovascular outcomes, especially new ischemic events. To identify patients with non-ST segment elevation acute coronary syndromes (NSTEACS) who benefit from an invasive revascularization strategy remains a challenge. We sought to determine if patients with high-risk NSTEACS who exhibited LLC have a greater reduction in long-term post-discharge myocardial infarction (MI) when managed under a revascularization invasive strategy (RIS) as compared with conservative strategy (CS). Methods Nine hundred seventy two consecutive patients with high-risk NSTEACS were treated unde…
