ABSTRACT
Objectives: In a retrospective study, we aimed to explore the prevalence of risk factors and trends of obstructive coronary artery disease (CAD) in Indian females <45 years of age compared to males of the same age group who underwent percutaneous coronary intervention (PCI). Materials and Methods: This was a retrospective, observational, multi-centre study of young Indian females and males (<45 years) who underwent PCI as per the guidelines at three high-volume centres in India. Results: In a group of 3656 patients under the age of 45 who had PCI, 3.1% of those with obstructive CAD were young women (n ¼ 113), while 6.9% were young men (n ¼ 254). Traditional risk factors such as hypertension (p ¼ 0.73), diabetes (p ¼ 0.61), and family history of premature CAD (p ¼ 0.63) were equally common in both genders, whereas dyslipidaemia (p < 0.001), overweight (p < 0.006), smoking (p ¼ 0.004) and, alcoholism (p < 0.001) were more common in young males. Acute coronary syndrome was the most common clinical presentation. Single-vessel disease was common, with the involvement of the left anterior descending artery as the most common angiographic feature. The prevalence of cardiogenic shock was 4.4% in females and 4.1% in males, while the in-hospital mortality rate was 1.77% in young females and 2% in young males. Conclusions: Obstructive CAD in young men and women accounted for 10% of all CAD cases requiring PCI. Although men account for the majority of patients, CAD in women under the age of 45 is not uncommon. Traditional risk factors are becoming more prevalent in younger women
ABSTRACT
Angiographically, a “dual LAD” is described as two distinct arteries supplying the vascular territory of the LAD in parts, identified as the short LAD/LAD1 and the long LAD/LAD2. Using an easy-to-understand three-step approach, Jariwala et al unveiled a novel classification strategy for dual LAD systems in an attempt to decrease ambiguity in diagnosis and management of the anomaly. As part of our research, we looked at a wide range of published cases and case series in the literature, and also those reported from our hospital. In our novel classification system, we divide dual LADs into three main groups based on their origin and vascular territory, each of which is further divided into subgroups based on the course of LAD1/LAD2 and the variable feature that is a distinguishing attribute of the type of anomaly to be specified. A review of 144 publications in the world literature revealed 340 patients eligible for the study. The median age was 58.8 years (SD - 11.42; range - 29e89) with male predominance (3.3:1). Cases in Group I comprised 60.6% of the total cases, followed by Group II (36.2%), and Group III (3.2%). Subgroup I-A was the most common in terms of dual LAD, followed by subgroup II-A. Acute coronary syndrome (45.5%) and chronic coronary syndrome (55.8%) were the most common clinical presentations in patients with significant coronary artery disease (30.8%).
