ABSTRACT

BACKGROUND: The limited availability of complex coronary intervention facilities and qualified operators, due to the high cost associated with chronic total occlusion (CTO) percutaneous intervention (PCI) equipment and a shortage of necessary skills, has led to a scarcity of capable medical centers in Pakistan. This study seeks to examine the outcomes and potential complications associated with CTO PCI procedures conducted at the Cardiac Catheterization Laboratories of a prominent national institute in Pakistan, which handles a large volume of cases. RESULTS: Three hundred and six patients were included in the study in the study period of six months. The mean age was 59.49 (± 9.16) years: 256 (83.66%) were male and 50 (16.34%) were female. CTO was successfully re-vascularized in 237 (77.5%) with a complication rate of 13.7%. Two hundred and ninety-eight (97.39%) patients underwent an antegrade approach, while RCA was the most common target vessel (47.71%). Diabetes was the only significant associated risk factor with CTO PCI failure (30.43% vs. 30.43%, P-value = 0.015). CONCLUSION: We achieved an excellent procedural success rate with a low complication rate. CTO procedural failure is associated with a higher complication rate, and diabetes is among the risk factors that lead to higher procedural failure.

ABSTRACT

BACKGROUND: Hypertension is a leading cause of morbidity among developing and developed countries. Hypertensive Retinopathy is a micro vascular complication of long standing hypertension while CAD is a macro vascular complication. The main objective of the study was to determine the association between worsening grade of hypertensive retinopathy with angiographic severity of coronary artery disease (CAD) measured by Syntax Score. METHODS: This was a cross sectional study which was conducted after approval from IRB. All patients with history of hypertension, who underwent coronary angiography, were included in the study. After a detailed history and physical exam, all included patients were subjected to fundoscopy. Patients were categorized into 4 groups according to Keith et al classification of hypertensive retinopathy: No HR, Mild HR, Moderate HR and Severe HR. Patients were also categorized into three groups on the basis of angiographic severity of CAD by syntax score (SS): Mild CAD (SS<22), Moderate CAD (SS: 22-32) and Severe CAD (SS>32). Data was analysed in SPSS Version 20.0. Categorical and continuous variables were described as frequencies/percentages and Mean±SD respectively. RESULTS: A total of 370 patients were included in the study out of which 205 were males with a mean age of 55.3±10.07 years. Mean duration of hypertension was 8.1±2.7 years with a mean SBP of 130.1±37.2 mmHg and mean DBP of 90.3±17.3 mmHg. Patients with no HR, mild HR, moderate HR and severe HR had a mean SS of 11.7±4.5, 17.1±3.9, 26.3±5.1 and 37.9±5.1 respectively. Significant association was found between HR and severity of CAD with a chi square value of 285.53 (p<0.001). PORs for worsening grade of HR with severity of CAD increased from 0.341 (p<0.001) for mild HR to 2.33 (p<0.001) times for severe HR. CONCLUSIONS: A higher grade of hypertensive retinopathy is significantly associated to a higher angiographic severity of CAD by syntax score.

ABSTRACT

OBJECTIVE: To determine the association between hypertensive retinopathy (HR) and post ST elevation myocardial infarction (STEMI) complications among successfully thrombolysed patients. STUDY DESIGN: A cohort study. PLACE AND DURATION OF STUDY: Cardiology Unit, Lady Reading Hospital, Peshawar, from June 2016 to December 2017. METHODOLOGY: Patients with history of hypertension for at least 5 years who presented with STEMI and were successfully thrombolysed, were included. On the basis of fundoscopy, patients were grouped into no, mild, moderate, and severe hypertensive retinopathy. Primary and secondary endpoints included a composite of death, re-MI, stroke, re-hospitalisation secondary to left ventricular failure, cardiogenic shock, arrhythmia, heart block, and ventricular septal rupture at 30 days and 4 months, respectively. Association between hypertensive retinopathy and post STEMI complications was determined by Chi-square test. Regression model was used to calculate relative risk of complications with hypertensive retinopathy. P <0.05 was taken as significant. RESULTS: A total of 118 patients with a mean age of 54.83 ±8.6 years were included in the study. Of these, 49.2% (n=58) were males. Moreover, 38.1% (n=45) of patients were grouped under no HR, 22.8% (n=27) under mild HR, 21.1% (n=25) and 17.7% (n=21) under moderate and severe HR, respectively. Primary endpoints achieved were 0% in no HR group and 19% in severe HR group x² = 18.1, p <0.001). Secondary endpoints were achieved in 2.2% in no HR group and 40.7%, 56% and 100% in mild, moderate and severe HR group, respectively, ( x² = 81.1, p <0.001). HR also increased the relative risk of complications by 3.17 times (p <0.001) and death by 1.75 times (p <0.001). CONCLUSION: Hypertensive retinopathy is an independent risk factor for post-acute STEMI complications in successfully thrombolysed patients and increased the relative risk for complications by 3.17 times.
