# Clinical, Angiographic, and Procedural Characteristics of Patients Undergoing Percutaneous Coronary Intervention: A Single-Center Study From Northeast India

## TL;DR

This study examines characteristics and outcomes of heart procedures in Northeast India, finding common risk factors and high success rates.

## Contribution

The study provides region-specific insights into PCI characteristics and outcomes in Northeast India.

## Key findings

- Most patients had hypertension and presented with acute coronary syndrome.
- Left anterior descending artery was most commonly involved, with high procedural success rates.
- Femoral access was predominantly used, and complications were relatively low.

## Abstract

Objective: This study aims to evaluate the clinical, angiographic, and procedural characteristics, as well as short-term outcomes, of patients undergoing percutaneous coronary intervention (PCI) at a tertiary care center.

Materials and methods: A prospective observational study was conducted at Gauhati Medical College and Hospital, Guwahati, Assam, between March 2020 and December 2021, enrolling 150 patients undergoing PCI. Baseline demographic details, risk factors, clinical presentations, echocardiographic findings, angiographic profiles, procedural characteristics, and outcomes were recorded. Statistical analyses were performed using SPSS Statistics version 21.0 (IBM Corp. Released 2012. IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp.).

Results: The mean age of the study population was 55 ± 12 years, with 135 (90%) being male. Hypertension (93 (62%)) and dyslipidemia (86 (57%)) were the most common risk factors. Acute coronary syndrome (ACS) with ST-elevation myocardial infarction was the most frequent presentation (107 (71.33%)). Femoral access was used in the majority of procedures (146 (97.33%)), and elective PCI was performed in 115 (76.77%) of patients. Single-vessel disease was observed in 79 (53.33%) cases, and significant involvement of the left anterior descending (LAD) artery was noted in 109 (72.67%) cases. Type B lesions were the most common in 113 (75.33%) patients. Overall, one patient (0.67%) died during hospitalization, while 149 (99.33%) were discharged stable. Procedural complications occurred in 27 (18%) of patients, with slow flow being the most frequent (10 (6.67%)).

Conclusions: This study highlights a high burden of risk factors and ACS presentations among PCI patients in Northeast India, with LAD being the most commonly involved artery. PCI was safe and effective with high success and low complication rates. Broader studies are needed to validate these findings.
