Cardiocerebral Infarction: A Single Institutional Series.

OBJECTIVES: Cardiocerebral infarction (CCI) is the rare occurrence of acute ischemic stroke (AIS) and acute myocardial infarction (AMI), either at the same time (simultaneous or synchronous) or one after the other (metachronous). The aim of this study is to describe the clinical profile, management and treatment outcomes of patients with CCI. MATERIALS AND METHODS: This is a 3-year cross-sectional study of patients with CCI describing their clinical presentation, management, and outcomes. The primary outcome measures were all-cause mortality and functional outcome measured with the modified Rankin Scale score (mRS) at discharge and at 30 days post-CCI. We also described the frequency of major and minor hemorrhagic events. RESULTS: Out of 1683 AIS patients and 1983 AMI patients admitted during our time period, 29 patients fulfilled the inclusion criteria (mean age 60 ±12, 79% males, median admission NIHSS 16 [range 1-26]). Of these, 20 (69%) had metachronous CCI while 9 (31%) had synchronous CCI. Most of the patients were given antithrombotics and only 14% were given reperfusion therapies. The all-cause mortality is 45% and 69% of which were cardiovascular deaths. Seventeen and 21% of CCI patients had a good functional outcome on discharge and at 30 days from CCI onset respectively. A total of 8 (28%) patients had hemorrhagic events. CONCLUSIONS: We present the largest single institutional series showing the prevalence rate of cardiocerebral infarction to be 0.79% (0.55% for metachronous, 0.25% for synchronous), with patients presenting as moderate-severe acute ischemic strokes and high-risk acute myocardial infarction. These patients have a high mortality rate with a significant proportion having cardiovascular deaths.

Thrombolysis Outcomes in Patients with Diabetes and Previous Stroke: A Meta-Analysis.

BACKGROUND: Intravenous tissue-type plasminogen activator (IVtPA) is a proven treatment for acute ischemic stroke; however, diabetes mellitus (DM) and previous cerebral infarction (PCI) were considered relative contraindications for thrombolysis within the 3-4.5 h period. OBJECTIVE: The study aimed to determine the safety and efficacy of IVtPA among diabetic patients with PCI presenting with acute ischemic stroke. METHODS: Studies which evaluated the outcome of IVtPA in terms of symptomatic intracerebral hemorrhage (sICH), functional outcome in modified Rankin scale, and death among diabetic patients with PCI presenting with acute ischemic stroke within the 3-4.5 h period were systematically searched until July 2019. Screening and eligibility criteria were applied. Risk of bias was evaluated using the Newcastle-Ottawa Scale. Odds ratios (ORs) with 95% confidence interval (CI) were used to compare measures of treatment effect. Mantel-Haenszel method and random-effects model were also employed. RESULTS: Four registry-based studies with a total of 44,572 patients were included for quantitative synthesis. Giving IVtPA among DM+/PCI+ patients did not result in significantly increased rate of sICH (OR, 1.09; 95% CI, 0.88, 1.36) compared to No DM+/PCI+ patients. However, there was significantly higher mortality (OR, 1.81; 95% CI, 1.60, 2.06) in the DM+/PCI+ group. Conversely, among those who survived, the DM+/PCI+ patients were more functionally independent at 3 months (OR, 0.76; 95% CI, 0.61, 0.94). CONCLUSION: Limited evidence suggests that thrombolysis in DM+/PCI+ patients does not result in significantly higher incidence of sICH and may improve functional independence. However, the significantly higher mortality in this group warrants an assessment of the individualized risk-benefit ratio in the use of IVtPA.

Concurrent validity of palpation and musculoskeletal ultrasound in evaluating the fascia of individuals with and without myofascial pain syndrome.

BACKGROUND AND PURPOSE: Palpation evaluates the fascia, a three-dimensional web of connective tissues. We propose altered fascia system displacement in patients with myofascial pain syndrome. This study determined the concurrent validity of palpation and musculoskeletal ultrasound (MSUS) videos played on Windows Media Player 10 (WMP) when evaluating the direction of the fascia system's displacement at the end of the cervical active range of motion (AROM). METHODS: This cross-sectional study used palpation as index test and MSUS videos on WMP as reference test. First, three physical therapists palpated right and left shoulders for each cervical AROM. Second, during cervical AROM, PT-Sonographer recorded the fascia system displacement. Third, using the WMP, the physical therapists evaluated the direction of skin, superficial and deep fascia displacements at the end of cervical AROM. MedCalc Version 19.5.3 determined the "exact" Clopper-Pearson Interval (CPI). RESULTS: We found strong accuracy between palpation and MSUS videos on WMP when determining the direction of skin displacement during cervical flexion and extension (CPI= 78.56 to 96.89). There was moderate agreement between palpation and MSUS videos on WMP when determining the direction of the skin, superficial fascia, and deep fascia displacements during cervical lateral flexion and rotation (CPI= 42.25 to 64.13). CONCLUSION: Skin palpation during cervical flexion and extension may be useful in evaluating patients with myofascial pain syndrome (MPS). It is unclear what fascia system was evaluated when shoulders were palpated at the end of cervical lateral flexion and rotation. Palpation as diagnostic tool for MPS was not investigated.

A Call for a Stroke Referral Network Between Primary Care and Stroke-Ready Hospitals in the Philippines: A Narrative Review.

BACKGROUND: The increasing stroke burden, inequity in the distribution of local neurologists, and the recent signing of the Universal Health Care Law in the Philippines provide compelling reasons for policy-makers to devise strategies to establish networks between primary care and stroke-ready hospitals. In this review, we explored the current literature and evidence that emphasized the roles of primary care providers (PCPs) and specialists, care transition, and telemedicine/teleneurology in various stages of stroke management. REVIEW SUMMARY: Clear delegation of stroke care responsibilities among PCPs and specialists is needed. Due to the limited number of specialists/neurologists, PCPs may contribute to addressing the insufficiency of community knowledge of acute stroke symptoms/risk factors, coordination with specialists and stroke-ready hospitals during acute stroke, and continuity of care during the poststroke stage. At present, the Philippines has only 49 stroke-ready hospitals; thus, an efficient and functional referral system for the care transition between the PCPs and specialists must be organized in our country. To provide remote access to expert stroke care for underserved areas and to increase thrombolysis utilization, the establishment of an effective telestroke system is indispensable. The empowerment of PCPs in teleneurology may assist in strengthening communication and networking with specialists with the ultimate goal of improving patient outcomes. CONCLUSIONS: In the era of Universal Health Care in the Philippines, the roles of PCP and specialists must be delineated. Increased access to stroke care through the establishment of networks among PCPs and stroke-ready hospitals (ie, via effective transition of care/teleneurology) must be prioritized especially in resource-constrained settings.

Re-examining the exclusion criterion of early recurrent ischemic stroke in intravenous thrombolysis: A meta-analysis.

BACKGROUND: Current guidelines preclude the administration of intravenous tissue plasminogen activator in patients with early recurrent stroke (prior ischemic stroke within three months). OBJECTIVES: This is a meta-analysis that aimed to determine the safety and efficacy of thrombolysis in patients with early recurrent stroke. SUMMARY OF REVIEW: Pubmed, Cochrane, Scopus, Embase and Clinicaltrials.gov were searched for studies comparing the outcomes of acute ischemic stroke patients undergoing intravenous thrombolysis between those with early recurrent stroke and those without. Random-effects meta-analysis was used to evaluate the outcomes in terms of symptomatic intracranial hemorrhage, mortality and good functional outcomes at 3 months (modified Rankin Score ≤ 2). Three retrospective cohort studies with a total of 48,459 thrombolysed patients (824 with early recurrent stroke and 47,635 without early recurrent stroke) were included in the meta-analysis. There was no significant difference between thrombolysed patients with early recurrent stroke and those without in terms of symptomatic intracranial hemorrhage (Odds Ratio [OR] 1.39, 95% Confidence Interval [CI] 0.75-2.58), mortality (OR 1.36, 95% CI 0.60-3.09) and good functional outcomes at 3 months (OR 0.74, 95% CI 0.47-1.16). CONCLUSIONS: Patients who received thrombolysis despite early recurrent stroke were not found to be at an increased risk of adverse outcomes compared to patients without early recurrent stroke. Our meta-analysis suggests that there is insufficient evidence to substantiate excluding patients with early recurrent stroke from receiving thrombolysis. Further studies to re-examine early recurrent stroke as an exclusion criterion for receiving thrombolysis are warranted.

Association of lipoprotein lipase gene polymorphisms with coronary artery disease among Filipinos.

Studies have shown association of lipoprotein lipase (LPL) polymorphisms with coronary artery disease (CAD); however, limited studies on the genetics of CAD have been done in the Philippines. Because of their effects on high-density lipoprotein and triglyceride metabolism, the G-allele of the Ser447X variant of LPL gene has been shown to be atheroprotective, while HindIII polymorphism has been shown to be pro-atherogenic. We assessed 1301 patients undergoing coronary angiography to determine the prevalence of HindIII and Ser447X polymorphisms and their association with angiographically significant CAD. Genotyping for HindIII and Ser447X variants were analyzed by real-time PCR. Multivariate analyses were performed to determine the interaction between LPL polymorphisms and risk factors of CAD. CAD+ group (72%) was predominantly male (76%) with a mean age of 60.17 ± 11.01 with hypertension (89%), dyslipidemia (84%) and smoking (54%) as the most common risk factors. HindIII carriage frequency among the CAD+ group was 20.3% with a genotypic distribution of 78.71% (T/T), 19.83% (T/G) and 1.46% (G/G). Ser447X carriage frequency among the CAD+ group was 8.0% with a genotypic distribution of 91.39% (C/C), 8.38% (C/G) and 0.23% (G/G). HindIII and Ser447X polymorphisms were both not significantly associated with CAD. LPL polymorphic allele HindIII was common, while Ser447X was rare. Present study did not show association of LPL polymorphisms with the development of CAD. However, among patients with dyslipidemia, presence of Ser447X allele is associated with an increased risk (OR 2.6; 95% CI 2.1-3.7; p value < 0.001) of developing CAD than those without LPL polymorphisms.

Sources and reasons for delays in the care of acute stroke patients.

OBJECTIVE: This study aimed to identify sources and reasons for delays in the care of our acute stroke patients. METHODS: Data on time interval from symptom onset or awareness to initial presentation, to neurology assessment, to performance of cranial CT scan, and demographic and medical factors associated with delays among stroke patients admitted at St. Luke's Medical Center from May to October 2000 were obtained by interview and record review. RESULTS: Of 259 patients (mean age 61.5+/-13.6 years, 43% females), 63% had infarction (INF), 32% intracerebral hemorrhage (ICH) and 5% subarachnoid hemorrhage (SAH). Fifty-nine percent presented within 3 h of symptom onset or awareness, 73% within 6 h (median=2 h). Patients with ICH presented earlier than those with infarction. Reasons for delayed consultation included failure to recognize symptoms as serious and stroke-related. A non-neurologist was initially consulted in 97% of cases. Median delay from presentation to neurology evaluation was 7.5 h. Median time from presentation to brain imaging was significantly shorter for patients brought to CT-equipped facilities (2 h) than for those needing transfer to other hospitals (11.5 h). CONCLUSIONS AND RECOMMENDATIONS: Patient delay in presentation is only one cause of delay in acute stroke care. Longer delays arise from healthcare-related factors such as delays in neurologist referral and neuroradiologic diagnosis. Professional and public education on the necessity of early neurologic evaluation and patient transport to CT-equipped "Stroke Centers" is recommended.
