Accuracy of quality of life questionnaire as a diagnostic tool for SARS-CoV-2 pulmonary sequelae.

Background: Follow-up after hospital discharge of SARS-CoV-2 survivors represents a huge burden on the healthcare system. We attempt to assess the utility of symptoms and health-related quality of life questionnaire (SF-12) to identify SARS CoV2 pulmonary sequelae. Methods: Prospective, non-interventional follow-up study. A cardiopulmonary exercise test, functional respiratory test (PFT), SF12 questionnaire were performed after hospitalization at six months after the first positive PCR smear. Results: 41 patients were included, female (39%), mean age 57.3 ± 13.7 years. 70% persisted with symptoms. 46% presented a maximum oxygen consumption below 80% of predicted. SF-12 physical domain score was significantly reduced in patients with altered PFT (32.7 vs. 45.9; p < 0.001) and obtained the best sensitivity and specificity to identify PFT alterations (AUC 0.862, Sensitivity 85.7%, Specificity 81.5%). Conclusions: SF-12 questionnaire shows high sensitivity and specificity to detect SARS CoV2 survivors with pulmonary function alterations.

Debut of an unusual liver cirrhosis.

Secondary or metastatic cardiac tumors are about 20-40 times more common than primary benign or malignant cardiac tumors. Cardiac metastases are more frequent in carcinomas, they usually appear in patients over 50 years and the involvement by gender is similar. Any tumor can cause cardiac or pericardial metastasis, although isolated or combined tumor invasion of the pericardium is more common. Transthoracic echocardiography (TTE) is the primary diagnostic procedure, followed by computed tomography (CT) and cardiac magnetic resonance imaging (MRI) to verify positive findings and to analyze other structures of the mediastinum and chest. Treatment of such tumors is generally associated with poor results and unfavorable prognosis. We report the case of an unusual cardiac metastasis.

Cardiac Relapse of Acute Myeloid Leukemia after Allogeneic Hematopoietic Stem Cell Transplantation.

Secondary or metastatic cardiac tumors are much more common than primary benign or malignant cardiac tumors. Any tumor can cause myocardial or pericardial metastasis, although isolated or combined tumor invasion of the pericardium is more common. Types of neoplasia with the highest rates of cardiac or pericardial involvement are melanoma, lung cancer, and breast and mediastinal carcinomas. Acute myeloid leukemia (AML) is the most common type of acute leukemia in adults. Initial treatment involves chemotherapy followed by consolidation treatment to reduce the risk of relapse. In high-risk patients, the treatment of choice for consolidation is hematopoietic stem cell transplantation (HSCT). Relapse of AML is the most common cause of HSCT failure. Extramedullary relapse is rare. The organs most frequently affected, called "sanctuaries," are the testes, ovaries, and central nervous system. We present a case with extramedullary relapse in the form of a solid cardiac mass.

Drug-eluting stents in patients on chronic hemodialysis: paclitaxel-eluting stents vs. limus-eluting stents.

BACKGROUND: Patients requiring chronic hemodialysis (HD) are at high risk for restenosis after percutaneous coronary intervention (PCI) with bare metal stents. Outcome data on drug-eluting stent (DES) implantation in HD patients are limited and suggest superiority of paclitaxel-eluting stents (PES) over limus-eluting stents (LES). METHODS: In total, 218 consecutive patients were prospectively enrolled. A comparison of post-PCI outcomes up to 2 years was carried out between patients receiving PES (n=62) and LES (n=156; SES n=112, EES n=44). The primary end point was 2-year major adverse cardiac events [MACE; death, Q-wave myocardial infarction and target lesion revascularization (TLR)]. RESULTS: Baseline characteristics were comparable. The overall prevalence of diabetes mellitus was 71%. On clinical follow-up to 2 years, MACE rates were similar [PES 32/51 (62.7%) vs. LES 77/132 (58.3%), p=0.59]; however, clinically-driven revascularization occurred more than twice as frequently in LES patients: TLR [PES 4/36 (11.1%) vs. LES 24/93 (25.8%), p=0.07] and target vessel revascularization [5/37 (13.5%) vs. 33/96 (34.4%), p=0.02]. Given that overall mortality was nominally higher for PES patients [31/50 (62.0%) vs. 61/127 (48.0%), p=0.09], a competing outcome analysis was implemented for TLR against mortality, which demonstrated that the trend for increased TLR with LES was no longer apparent (p=0.282). On multivariable adjustment, only diabetes mellitus was independently associated with TLR (use of PES was not). CONCLUSIONS: Patients on chronic HD experience high rates of clinically driven TLR despite DES implantation. Use of PES does not demonstrate a significant advantage over LES in this population.

Clinical outcomes after treating acute coronary syndrome patients with a drug-eluting stent: results from REWARDS-EMI (Endeavor for Myocardial Infarction Registry).

BACKGROUND: Drug-eluting stents have shown promising clinical results in the treatment of acute coronary syndrome (ACS) patients. We aimed to evaluate the long-term outcome of Endeavor zotarolimus-eluting stent (EZES) implantation in an ACS population and to compare these results with those obtained in patients treated with sirolimus-eluting (SES) and paclitaxel-eluting stents (PES). METHODS: This prospective study included 1481 consecutive ACS patients (72% myocardial infarction, age 65 ± 13 years, 62% male) treated with a drug-eluting stent: (SES, n=925; PES, n=417; EZES, n=139). The primary end point was major adverse cardiac events (MACE) at 2 years, defined as the composite of death, myocardial infarction, and target vessel revascularization. Two-year follow-up was obtained in all patients. RESULTS: Baseline clinical and angiographic characteristics were mostly similar. Unadjusted 2-year MACE and death rates were lower in the EZES group than in the SES and PES groups (MACE: 18.7% vs. 25.3% vs. 30.2%, p=0.02; death: 10.1% vs. 16.4% vs. 22.2%, p=0.002, respectively). The rate of definite stent thrombosis at 2 years was lower in the EZES group without statistically significant difference (0.7% vs. 2.9% SES vs. 1.7% PES, p=0.16). After adjusting for differences in baseline characteristics, EZES use was an independent correlate for 2-year MACE (vs. SES, hazard ratio 0.65, p=0.049; vs. PES, hazard ratio 0.57, p=0.01). CONCLUSION: In an ACS patient population, a lower long-term MACE rate was observed in patients treated with an EZES when compared to treatment with first-generation drug-eluting stents. The use of EZES in contemporary practice has excellent long-term outcome in terms of low rates of revascularization and clinical events.

The independent value of a direct stenting strategy on early and late clinical outcomes in patients undergoing elective percutaneous coronary intervention.

OBJECTIVES: This study aimed to compare percutaneous coronary intervention (PCI) with direct stenting (DS) to balloon predilatation (PD) for patients undergoing elective PCI to determine whether there is an independent value for DS with regard to clinical outcomes. BACKGROUND: The safety of PCI with DS has been established, but the independent advantages of this technique are not entirely clear. METHODS: Patients undergoing elective PCI from January 2000 to December 2010 were included. The postprocedural and late clinical outcomes of 444 patients who underwent PCI with DS were compared with a propensity-matched population of 444 subjects treated with PD. RESULTS: The two groups were well matched to 27 baseline clinical, procedural, and angiographic characteristics, thus allowing for a more accurate evaluation of the independent value of the stenting technique. Intravascular ultrasound was used in more than 60% of interventions in both groups. PCI performed with PD were longer (DS 45 ± 19.28 vs. PD 56 ± 23.72 minutes, P = 0.001), used more contrast (DS 154 ± 65.88 vs. PD 186 ± 92.84 cc, P = 0.001), and more frequently used balloon postdilation (DS 0% vs. PD 27.3%, P = 0.001). The incidence of periprocedural myocardial infarction (PPMI) was similar between DS- and PD patients (5.3% vs. 5.4%, P = 0.91). Likewise, the 1-year rates of major adverse cardiac events (8.4% vs. 6.3%, P = 0.25), target lesion revascularization (3.9% vs. 2.5%, P = 0.24), and definite stent thrombosis (0.2% vs. 0.9%, P = 0.37) were similar among DS and PD patients, respectively. CONCLUSION: During elective PCI, DS decreases overall procedure time and resource utilization, but fails to reveal an independent clinical advantage as there is no demonstrable benefit in regard to the incidence of PPMI, restenosis, or overall clinical outcomes up to 1-year of follow-up.

Utility of intravascular ultrasound guidance in patients undergoing percutaneous coronary intervention for type C lesions.

BACKGROUND: Percutaneous coronary intervention (PCI) of complex lesions (i.e., American College of Cardiology/American Heart Association class type C) remains challenging and the outcome may be compromised. The use of intravascular ultrasound (IVUS) to guide PCI was suggested to improve outcome. METHODS: A cohort of 1,984 patients who underwent PCI to type C lesions in our center from April 2000 to March 2010 was identified. Using propensity score matching with clinical and angiographic characteristics, we identified 637 patients who underwent IVUS guidance and 637 patients who had only angiographic guidance PCI. Major adverse cardiovascular events (MACE), a composite end-point of all-cause mortality, Q-wave myocardial infarction and target lesion revascularization, were compared between the 2 groups. RESULTS: After propensity score matching, baseline clinical and angiographic characteristics were well matched. Patients undergoing IVUS-guided PCI had less predilatation and more postdilatation, and were treated more often with cutting balloon. Final diameter stenosis was significantly smaller in the IVUS-guided group (3 ± 11% vs. 7 ± 19%, P < 0.001), resulting in higher angiographic success compared with the non-IVUS-guided group (97.9% vs. 94.8%, P < 0.001). The incidence of MACE was significantly lower in the IVUS-guided group compared to the angiography-guided group (11.0% vs. 15.6%, P = 0.017) as was cardiac death (1.9% vs. 4.4%, P = 0.010). CONCLUSION: IVUS-guided PCI for complex type C lesions is associated with better outcome and should be considered for these lesions.

Impact of drug-eluting stents on distal vessels.

BACKGROUND: Previous studies have not addressed vessel response >5 mm distal to the stent edge. Therefore, we investigated the impact of paclitaxel-eluting stents (PES) versus bare metal stents (BMS) on distal vessels in the serial intravascular ultrasound substudies of TAXUS IV, V, and VI. METHODS AND RESULTS: TAXUS IV, V, and VI were double-blind, randomized, multicenter, controlled trials comparing PES with BMS. In their intravascular ultrasound substudies, 103 patients (54 BMS, 49 PES) had intravascular ultrasound data ≥10 mm distal to the stent both postprocedure and at 9 months follow-up. Baseline characteristics were similar between the 2 groups. Multilevel modeling was used to account for the variation between patients and within patients among distal segments. Effect of stent type, time, and their interaction was tested using a mixed effect model controlling for distal segments. Postprocedure lumen and vessel were not significantly different between PES versus BMS; however, lumen (P=0.006) and vessel (P=0.0001) were significantly reduced for BMS at 9-month follow-up but not for PES. Conversely, there was a significant plaque increase from postprocedure to 9-month follow-up for PES (P=0.0008) but not for BMS. These vessel responses were statistically consistent among 0- to 5-mm versus 5- to 10-mm versus 10- to 15-mm segments distal to the stent in both groups. CONCLUSIONS: PES use was associated with plaque increase from baseline to 9-month follow-up >5 mm distal to the stent along with positive remodeling, whereas BMS use was associated with negative remodeling and no plaque increase. These vessel responses were consistent in 5-mm long subsegments: 0 to 5 mm versus 5 to 10 mm versus 10 to 15 mm distal to the stent. CLINICAL TRIAL REGISTRATION: URL: HTTP://WWW.CLINICALTRIAL.GOV.
