Coronary artery diseasePrevalence of Narrowing ≥50% of the Left Main Coronary Artery Among 17,300 Patients Having Coronary Angiography
Section snippets
Methods and Results
The data of 17,323 consecutive patients who underwent coronary angiography for any reason at our institution in Northern Greece from January 1, 1984 to December 31, 2003 were assessed through our database and retrospectively analyzed. The demographic parameters, in particular age and gender, of the investigated patients were recorded and summarized. All the angiograms were evaluated by an independent, expert interventional cardiologist blinded to the patients’ clinical and laboratory data. The
Discussion
The large number of patients included in our study (n = 17,323) enabled us to come to a secure and solid estimation regarding the prevalence of LMSS in the studied population. The prevalence of LMSS in our series (n = 823, 4.8%) was within the range of prevalence rates reported in previous studies.1, 2, 3, 4, 5 Several studies in the past6, 7 reported the absence of a substantial gender difference in the prevalence of LMSS in patients with angiographically significant coronary disease, although

Intravascular ultrasound-guided versus angiography-guided percutaneous coronary intervention in unprotected left main coronary artery disease: A systematic review
2024, Cardiovascular Revascularization MedicinePredicting left main stenosis in stable ischemic heart disease using logistic regression and boosted trees
2023, American Heart JournalCitation Excerpt :Only a small number of studies have focused specifically on left main disease prediction among patients with stable ischemic heart disease. A study with more than 17,000 patients undergoing coronary angiography in Greece has found that those with significant left main coronary artery disease were more likely to be male and older compared to patients without left main disease.23 Recently, the ISCHEMIA investigators reported a clinical prediction model of left main coronary artery disease using CCTA as the gold standard among 5,146 patients, mainly with moderate or severe ischemia.7
Sex Differences in Clinical Outcomes Following Percutaneous Coronary Intervention of Unprotected Left Main Coronary Artery: A Systematic Review and Meta-Analysis
2021, Cardiovascular Revascularization MedicineCitation Excerpt :Based on 2016 estimates, 6.7% of Americans ≥20 years of age have CHD which approximates to around 18 million [1]. Significant left main coronary disease (LMCD), defined as left main (LM) coronary artery narrowing of ≥50% on coronary angiography, is noted in 3–7% of patients undergoing coronary angiography and is associated with higher rates of clinical events [2,3]. Despite the lower overall prevalence of LMCD in women, isolated LMCD is more frequent in women compared to men [3].
