RESUMEN

Objective: Chronic kidney disease (CKD) patients are at high risk of heart failure (HF) and both share similar risk factors, including diabetes and elevated blood Pressure (B.P). Aim of this study was to determine the impact of sacubitril/valsartan on the quality of life (QOL) and ejection fraction (EF) of patients with HF with and without CKD. Methods: Single center (Doctors Hospital Lahore), observational study with longitudinal follow up, on 104 HF patients from July 2019 to July 2020. HF was diagnosed on both clinical and echo parameters. New York Heart Association Class II-IV, EF less than or equal to 40% HF with reduced EF and stage three CKD patients were included. Sacubitril/Valsartan was prescribed at a starting daily dose of 50mg and then up titrated to 400mg. Patients were followed up with clinical evaluation, QOL assessment, echocardiography and biochemical profile at one, four, eight and 12 months. Results: Gender, age, and diabetes mellitus between CKD and non-CKD patients were noted to be statistically different, defined as p<0.05. CKD patients' QOL increased from 45.15 to 57.57 from baseline to 12 months (p-value<0.01). Non-CKD patients' QOL increased from 48.07 to 56.25. In CKD patients, EF increased from 27.87% to 29.29% from baseline to 12 months (p-value 0.03) whereas in non-CKD patients EF improved from 29.42% to 31.43%. Conclusion: Sacubitril/ valsartan improves QOL in patients of HF with reduced EF both with and without CKD. Clinical improvement was independent of Left Ventricular EF as measured by QOL. Thus, QOL is a useful tool to assess the drug's beneficial effect.

RESUMEN

Objective: Prolonged intensive care unit stay not only increases hospital cost but it also prevents hospital equipment to be used by other patients who need them. The aim of this study was to identify factors that affect the duration of intensive care unit stay in post coronary artery bypass grafting patients with chronic kidney disease. Method: This is a single centered observational prospective study done on 191 post coronary artery bypass grafting patients from June 2018 to April 2019 at Cardiac Surgery Unit of Doctor's hospital and medical center, Lahore, Pakistan. Patients above 18 years with and without chronic kidney disease were included. Results: Mean age of the patients was 57.83 years (± 9.862 SD. Logistic regression analysis shows that patients with post op arrhythmias had the strongest positive association with prolonged intensive care unit stay (OR:11; p value :<0.01), followed by recent myocardial infarction less than 90 days pre coronary artery bypass grafting (OR:5.93; p value:<0.01), shock (OR:3.93;p value:0.04) and acute kidney injury (OR :2.08;p value:0.04). 37.5% chronic kidney disease patients with recent myocardial infarction less than 90 days pre coronary artery bypass grafting and 51.4% patients of chronic kidney disease found with acute kidney injury, showed significant association with p values less than 0.05. Conclusion: Post op arrhythmias, recent myocardial infarction, shock and acute kidney injury are independent risk factors causing prolonged intensive care unit stay in post coronary artery bypass grafting patients.

RESUMEN

Chronic kidney disease (CKD) patients are at high risk of developing cardio vascular disease. Left atrial volume index (LAVi) is an indicator of left ventricular diastolic dysfunction. We conducted this study to find out the correlation of LAVi and other echocardio- graphic parameters with estimated glomerular filtration rate (eGFR). We prospectively enrolled 170 individuals: 69 patients with CKD and 101 controls. Echocardiographic parameters including systolic and diastolic volumes of left ventricle, LAVi, ejection fraction (EF), pulmonary artery systolic pressure (PASP), and E/e ratio were measured in all participants. The demographic, clinical, and echocardiographic parameters were examined. From the total of 170 individuals, 69 (40.5%) patients had CKD and 101 (59.5%) had normal renal profile. There were 38 (55.07%) males in the CKD group and 71 (70.29%) in the control group. Patients with CKD had higher median LAVi [33.33 mL/m2 ± 11.71 vs. 22.54 mL/m2 ± 5.82; P < 0.001], higher median E/e ratio [10.41 ± 6.28 vs. 7.48 ± 2.28; P < 0.001], higher median PASP [42.47 ± 13.64 vs. 33.59 ± 12.51; P < 0.001], and lower median EF [52.79% ± 14.37 vs. 60.7% ± 8; P < 0.001]. There was a statistically significant negative correlation of eGFR with LAVi (r = -0.515, P < 0.001), PASP (r = -0.44, P = 0.001), and E/e ratio (r = -0.331, P = 0.001). Patients with CKD have higher LAVi, PASP, and E/e ratio and lower EF as compared to individuals without CKD. There is a significant negative correlation between eGFR and LAVi.

RESUMEN

BACKGROUND: Mitral Annular Calcification (MAC) is a degenerative process involving the mitral valve and is a marker of advanced cardiovascular disease. Prevalence in the general population is upto 10% and increases in advanced age, diabetes mellitus, chronic kidney disease (CKD), end stage renal disease (upto 40%) and mitral valve prolapse.The aims of this study were to assess the prevalence of MAC in CKD5D patients and correlate with patients' characteristics. METHODS: Echocardiograms were obtained in 84 hemodialysis patients. Association of MAC with various patient characteristics was studied. Data was analysed using SPSS-22. RESULTS: The mean age of the patients was 63.38±12.3 years and 48 (57%) were males. Sixty-eight patients (81%) had DM and 79 (94%) had hypertension. MAC was present in 37 out of 84 (44%) patients. Sixty-four (72%) had IHD. The presence of MAC correlated significantly with IHD (Odds Ratio 6.42, p=0.006). Mean follow up of the patients was 30.30±29.22 months and 37 (44%) suffered mortality during this period. Patients on dialysis for longer than 36 months had an elevated risk of developing MAC (OR=3.32, p=0.019). Patients with the following risk factors: serum PO4 greater than 5.5 (OR=2.03), DM (OR=1.95), HTN (OR=3.35), Age >60 (OR=1.83), AFIB (OR=1.28); had an observable increase in incidence of MAC with time but they weren't statistically significant. CONCLUSIONS: Mitral Annular Calcification is common in hemodialysis patients and correlates significantly with IHD. Our findings support the recommendation by KDIGO 2017 guidelines on Mineral and Bone Disease on the use of echocardiography for the detection of valvular calcification.
