Assessing in-hospital mortality and predictors in Patients with contrast-induced nephropathy Following primary percutaneous coronary Intervention.

BACKGROUND: The contrast-induced nephropathy (CIN) is a common complication of primary percutaneous coronary intervention (PCI) it has been reported to be associated with an increased risk of mortality. The study reported the in-hospital mortality among patients who developed CIN after primary PCI. METHODS: This descriptive cross-sectional study was conducted on a sample of consecutive who developed CIN after primary PCI at a tertiary care cardiac hospital in Karachi, Pakistan. The CIN was defined as either a relative increase of 25% or an absolute increase of 0.5 mg/dL in post -procedure serum creatinine within 72 hours. The in-hospital mortality status was recorded and clinical and demographic predictors of in-hospital mortality were identified with the help of binary logistic regression analysis. RESULTS: In the study sample of 402 patients, 74.1% (298) were male and the mean age of the study sample was 59.4±11.5 years. The in-hospital mortality rate was 9.7% (39). On multivar iable analysis, an increased risk of mortality was found to be independently associated with inferior wall myocardial infarction (IWMI) with right ventricular (RV) infarction, intra-procedure arrhythmias, and pump failure with an adjusted odds ratio of 3.63 [95% CI: 1.31-10.08; p=0.013], 5.53 [95% CI: 1.39-22.06; p=0.015], and 8.94 [95% CI: 3.99-20.02; p<0.001], respectively. CONCLUSIONS: In conclusion, there is a high rate of mortality for patients who develop CIN after primary PCI, and the risk of mortality is further aggravated by the presence of IWMI with RV infarction, intra-procedure arrhythmias, and pump failure.

Incidence of Hyperuricemia in Patients with Acute Myocardial Infarction - A Case-Control Study.

Introduction Various researches have stated the correlation between serum uric acid (sUA) and cardiovascular disease (CVD); however, no local studies are available. In this study, we will determine the prevalence of hyperuricemia in patients with acute myocardial infarction and compare with the control group. Methods This case-control study was conducted from March to November 2019 in the tertiary care hospital in Pakistan. In all, 119 patients with acute myocardial infarction were enrolled in this study, and 119 controls were identified from the outpatient department. Their sUA levels were measured within 24 hours of acute myocardial infarction. Results The mean sUA levels were significantly higher in patients with acute myocardial infarction (AMI) in comparison to the control group (6.17 ± 2.12 vs. 5.51 ± 1.89, p-value; 0.01). Overall, there were more patients with hyperuricemia in the case group compared to the control group (47.89% vs. 33.6%, p-value = 0.04) Conclusion In this study, after adjustment of other known factors, hyperuricemia is associated with AMI. Efforts should be made to include screening for hyperuricemia in patients with a high risk of myocardial infarction.

Association of Leptin With Obesity and Insulin Resistance.

Introduction Leptin, a hormone released by the body to regulate energy balance by inhibiting hunger, decreases fat storage in adipocytes. Leptin is thought to play some role in obesity and insulin resistance. In this study, our aim is to see the association of leptin with obesity and insulin resistance. Methods This case-control study was conducted in a tertiary care hospital in Pakistan from January 2020 to April 2020. Ninety-two participants with BMI greater than 25 kg/m2, with no known comorbidities were enrolled in the study after informed consent. Ninety-two participants, who came to the outpatient department without a history of chronic disease, with BMI less than 25 kg/m2 were enrolled as a control group. Data were collected via self-structured questionnaires. Their blood was drawn and sent to the laboratory for cholesterol levels, insulin resistance and leptin levels. Results Serum leptin levels (51.24 ± 18.12 vs. 9.10 ± 2.99: p-value, < 0.0001), serum cholesterol levels (198.2 ± 32.1 vs. 151.2 ± 21.2, p-value < 0.0001) and insulin resistance (7.9 ± 2.1 vs. 6.3 ± 1.9, p-value < 0.0001) were higher in obese patients. Conclusion As per the results of this study, obesity was associated with increase serum leptin levels and insulin resistance. Further multi-centric studies are required to prove the possible relationship, which might help devise plans to manage obesity.

Comparison of Outcomes of Percutaneous Coronary Intervention Versus Coronary Artery Bypass Grafting.

Introduction Percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) are two common treatment options used in patients suffering from coronary artery disease. Selection and favorability of one over the other depend on individual clinical scenarios. The purpose of this study is to compare outcomes after treatment with PCI and CABG. Methods This longitudinal observational study was conducted from April 2018 to July 2019 in a cardiovascular unit of a tertiary care hospital. Participants who were eligible for revascularization were randomized either to receive stent (PCI) or surgery (CABG). Patients were then followed up for 12 months for the development of all-cause mortality and major adverse cardiovascular events (MACEs). Results At 12 months, patients randomized to the PCI group had an increased risk of repeat revascularization (21.3% vs. 7.4%; p = 0.007), whereas a similar number of patients in both groups died (3.8% vs. 3.7%), suffered myocardial infarction (7.6% vs. 5.6%), or had a cerebrovascular accident (3.8% vs. 2.8%). Conclusions This study showed that PCI had an increased risk of repeat revascularization compared to CABG. However, both had comparable significance in the development of MACEs. Nevertheless, there is a need for further study to better assess the outcomes of either, especially in the long run.

Risk of Major Adverse Cardiovascular Events in Patients With Rheumatoid Arthritis.

Introduction Rheumatoid arthritis is a chronic, inflammatory, and multisystem disease, which, along with the joints, can involve the cardiovascular system. The treatment of rheumatoid arthritis or rheumatoid arthritis itself can lead to atherosclerosis, which is considered one of the major causes by which it can affect the cardiovascular system. In this study, we will assess the risk of cardiovascular events in patients with rheumatoid arthritis as compared to the general population. Method This case-control study was conducted from January 2018 to November 2018. Two-hundred twenty-two (222) patients with diagnosed rheumatoid arthritis were included as cases in the study. Two-hundred eleven (211) patients were included in the study as the control group (patients without rheumatoid arthritis). All the data were recorded in a self-structured questionnaire. Result Participants with rheumatoid arthritis also showed an increased risk of myocardial infarction (MI) by an odds ratio of 2.50 (95% CI; 0.77-8.14). There was also an increased risk of cardiovascular death in participants with rheumatoid arthritis by an odds ratio of 1.99 (0.58-6.71). Conclusion The study suggests that rheumatoid arthritis along with joint inflammation can also affect the cardiovascular system. Hence, a multidisciplinary team of rheumatologists and cardiologists should manage patients suffering from rheumatoid arthritis, which will improve morbidity and mortality in such patients.

Evaluation of Risk Factors Associated with Reinfarction: A Multicenter Observational Study.

INTRODUCTION: Reinfarction after incidence of myocardial infarction is a serious complication and is responsible for high mortality. Various factors are responsible for reinfarction including smoking, prior procedures or surgeries, and use of medications such as aspirin, ß-blocker, and angiotensin-converting enzyme Iihibitor or angiotensin receptor blockers. MATERIAL AND METHODS: This prospective study was conducted with 243 participants. Participants were divided into two groups: patients who had a reinfarction during hospital and patients who did not. RESULTS: There were 142 (58.4%) men and 101 (41.6%) women in the study. A total of 17 (6.9%) patients had reinfarction. Age (68.4±10.9 vs. 64.4±11.8; 0.001), diabetes (47.05% vs. 22.12%; 0.02), and history of myocardial infarction (29.5% vs. 11.4%; 0.02) were identified as risk factors for reinfarction Conclusion: Our study reports that certain parameters such as age, obesity, diabetes mellitus,, and history of myocardial infarction can be used to assess the risk of reinfarction among these patients.

Depression and Anxiety as a Risk Factor for Myocardial Infarction.

INTRODUCTION:  Patients having a cardiovascular disease experience negative states of psychology. An increased incidence of coronary artery disease is attributed to both depression and anxiety. MATERIALS AND METHODS:  In this retrospective study, the Hospitalized Anxiety and Depression Scale (HADS) was used to determine anxiety and depression in stable patients of myocardial infarction (MI) at the time of their discharge. All responses were based on the patients' perceptions two weeks prior to acute MI event. SPSS version 21.0 was used for data entry and analysis. RESULTS: The mean age of the participants in our study was 49.09±5.61 years. About 52.83% (n=28) and 58.49% (n=31) participants suffered from anxiety and depression two weeks prior to their myocardial infarction. CONCLUSION: Depression and anxiety can be a risk factor for myocardial infarction in susceptible individuals. Attention should be given to mental well-being, and a multi-disciplinary management approach should be taken for these patients including psychiatry and psychology.

Comparison of Lipid Profile in Patients With and Without Acute Myocardial Infarction.

Introduction There is ample data available to determine the impact of deranged lipid values of acute myocardial infarction (AMI); however, there is a paucity of data from low-income countries like Pakistan. In this study, we aim to determine the correlation of lipid values with AMI. Materials and methods This case-control study was conducted from 1 February 2019 to 30 October 2019 in a tertiary care hospital in Sukkur, Pakistan. There were a total of 421 participants divided into two groups; Case Group (patients with AMI, n=212) and Control Group (patients without AMI, n=209). Results Total cholesterol and low-density lipoprotein (LDL) were significantly higher in patients with AMI and HDL was lower. There was no significant difference between triglycerides in both groups. Conclusion Dyslipidemia is an important risk factor for AMI. There is a need for more large scale multi-center studies to further understand the role of lipid profile in AMI and the various factors that influence it.

Comparison of Nebivolol and Bisoprolol for Cardiovascular Mortality in Hypertensive Patients.

Introduction Beta-blockers again are now considered as first-line therapy for various cardiovascular diseases. In this study, we compare the cardiovascular event between two beta-blocker, i.e. Nebivolol and Bisoprolol. Materials and Methods It is a two-arm open-label randomized prospective study that was conducted from 1st Jan 2016 to 30th July 2019 in tertiary care hospital, Nawabshah. One thousand and fifty-six (n=1056) hypertensive patients were enrolled after informed consent, which were randomized into two equal groups. Patients were followed up for one year. Results Comparison between Nebivolol and Bisoprolol showed that all-cause mortality (9.8% vs 11.48%), cardiovascular mortality (5.4% vs 7.0%), all-cause hospitalization (14.4% vs 16.3%), and cardiovascular hospitalization (9.8% vs 12.09%) was numerically lower in nebivolol but the difference was not statistically significant. Conclusion Further large scale multicentric trials with a longer follow up period are needed to compare various beta-blockers for cardiovascular event.
