From Heartbreak to Heart Disease: A Narrative Review on Depression as an Adjunct to Cardiovascular Disease.

Patients with cardiovascular disease (CVD) commonly have subclinical depression and are often delayed in their diagnosis. Literature suggests an increased association of depression and adverse cardiovascular events like myocardial infarction and heart failure. Prevalence of depression in developed countries is approximately 16.6%, and it confers higher cardiovascular mortality even after attrition bias and confounding factors are eliminated. Pharmacological and cognitive-behavioral therapy have been extensively studied, and are generally safe and effective in alleviating depressive symptoms in patients with CVD. However, their impact on cardiovascular outcomes is still unclear. Results of randomized controlled trials have shown antidepressants, especially selective serotonin reuptake inhibitors, to be safe and effective for healing a "broken heart." This review outlines the prevalence of depression in patients with CVD, the pathophysiological mechanism causing cardiovascular events with depression, and a link between depression and CVD. There is a wealth of literature explaining the precursor of CVD in depression, and like all chronic diseases, inflammation seems to be the culprit in this case as well.

Elevated D-Dimers and Right Ventricular Dysfunction on Echocardiography for Diagnosis of Pulmonary Embolism: A Validation Study.

Background There is an increasing need to explore other non-invasive techniques for the diagnosis of pulmonary embolism in resource-limited countries. Objective To assess the validity of elevated D-dimer levels and right ventricular (RV) dysfunction on echocardiography in predicting definite massive pulmonary embolism among patients diagnosed with massive pulmonary embolism using computed tomography (CT) pulmonary angiography as the gold standard. Methods The patients with acute massive pulmonary embolism on CT pulmonary angiography were included. The participants underwent 12-lead electrocardiography, assessment of D-dimer levels, and bedside echocardiography to determine right ventricular dysfunction. The data were recorded on a proforma and analyzed using IBM SPSS software version 26.0 (IBM Corp., Armonk, NY). Results There were 160 patients in the study. The mean age was 49.19 ± 14.89 years. Elevated D-dimer levels were seen in 80.60% of the patients whereas ventricular dysfunction on echocardiography was seen in 90.00% of the patients. The sensitivity and specificity of elevated D dimer levels were 78.99% and 14.60%, respectively. The positive predictive values (PPV) and negative predictive values (NPV) for elevated D-dimer levels were 72.87% and 19.35%, respectively. In contrast, the sensitivity of ventricular dysfunction was 94.96% and specificity 24.39%. PPV was found to be 78.47% and NPV was 62.50%. Conclusion Positive D-dimer levels and ventricular dysfunction on echocardiography are sensitive enough to consider the diagnosis of massive pulmonary embolism but lack adequate specificity, thus, necessitating the presence of other noninvasive tests.

Adverse Events in Primary Percutaneous Coronary Angioplasty With Drug-Eluting Stents Compared With Drug-Coated Balloons: A Retrospective Outlook.

Objective To compare drug-eluting stents (DES) with drug-coated balloons (DCBs) in terms of major adverse cardiovascular and cerebrovascular events (MACCE) in patients who have undergone primary percutaneous coronary intervention (PPCI). Methodology Out of 210 angioplasties in six months, 80 patients were included; 40 in DES and 40 in DCB, respectively. All had a successful PPCI. It was defined as the achievement of thrombolysis in myocardial infarction (TIMI) grade II/III with <20% residual stenosis for the DES and TIMI grade II/III with <30% residual stenosis for the DCB. Any subsequent MACCE during the ensuing six months were assessed from emergency/outpatient records during their subsequent hospital visits, hospital registry, and telephonic interviews. Results The mean age in the DES group was 54.83 + 8.72 years while it was 56.8 + 8.9 years in the DCB group. The left anterior descending artery (LAD) was the culprit artery in the majority of the cases in both groups. The mean diameter of DES and DCB was 3.17 + 0.38 mm and 2.75 + 0.53 mm, respectively. Overall, 15 adverse events were seen in the DES group and 16 in the DCB group. The difference was insignificant (P-value = ≥ 0.999). There were nine hospitalizations due to chest pain in the DES group and eight in the DCB group. Total vessel revascularization (TVR) was seen in two patients in the DES group and three patients in the DCB group. None of the patients suffered a stroke. All variables of MACCE were non-significant (P-value = ≥ 0.999). Conclusion DCB appears to be non-inferior to DES in PPCI at a median follow-up of six months.

Clinical Outcomes of Mechanical Prosthetic Valve Thrombosis.

Objective To evaluate characteristics and outcomes of patients presenting with mechanical prosthetic valve thrombosis in a tertiary cardiac center in Pakistan. Methods This was a prospective and interventional study conducted at Rawalpindi Institute of Cardiology over a period of two years. The clinical characteristics of patients presenting with clinical suspicion of prosthetic valve thrombosis were recorded. They were, then, subjected to streptokinase, redo surgery and heparin based on their hemodynamic stability, thrombus burden and surgical risk. The patients were then followed for the outcomes of the study. Results Out of 576 patients with mechanical valve replacement during the study period, 70 patients had developed prosthetic valve thrombosis. Out of 70 patients, there were 41 female (58.50%) and 29 male (41.50%) participants. The mean age of the participants was 48.40±15.00 years. The overall incidence of mechanical prosthetic valve thrombosis was 12.15%. There were 30 patients (42.80%) with a suboptimal international normalized ratio (INR) and 28 patients (40.00%) were non-compliant to warfarin therapy. The overall incidence of adverse clinical outcome was 18.00%, while the overall mortality rate was 10.00%. The mortality was higher for patients who underwent redo surgery (16.60%) as compared to patients who had received fibrinolytic therapy (9.60%). Conclusion Poor compliance with warfarin and suboptimal INR are the important factors causing mechanical prosthetic valve. Because of lower mortality rate, fibrinolysis with streptokinase is a reasonable treatment option for mechanical prosthetic valve thrombosis.
