Association of oily fish and nonoily fish intakes with all-cause mortality and cause-specific mortality: a large population-based prospective study.

BACKGROUND: There are inconsistent results of cohort studies analyzing the association between fish intake and mortality. OBJECTIVE: This study was performed to explore the association of oily fish consumption and nonoily fish consumption with all-cause mortality and cause-specific mortality. METHODS: A total of 431,062 participants from the UK Biobank who were without cancer or cardiovascular disease (CVD) at baseline between 2006 and 2010 were included in this study, and they were followed up through 2021. We constructed Cox proportional hazard models to calculate the hazard ratio (HR) and 95% confidence interval (CI) to assess the correlation of oily fish and nonoily fish intakes with mortality. Then, we performed subgroup analyses, and sensitivity analyses were developed and performed to examine the robustness of this study. RESULTS: Among the participants, 383,248 (88.9%) and 410,499 (95.2%) consumed oily fish and nonoily fish, respectively. Compared with the participants who did not consume oily fish, the adjusted HRs for the association of oily fish consumption (1 serving/week) with all-cause mortality and CVD mortality were 0.93 (0.87 to 0.98; p < 0.05) and 0.85 (0.74 to 0.98; p < 0.05), respectively. The multivariable-adjusted HRs of all-cause mortality for those who reported consuming < 1 serving/week of oily fish were 0.92 (0.86 to 0.98; p < 0.05). CONCLUSION: Compared with participants who reported never consuming oily fish, the consumption of oily fish with 1 serving/week was more beneficial for all-cause and CVD mortality.

[Clinical value of the evolution of left ventricular global strain in anterior myocardial infarction patients treated with emergency percutaneous coronary intervention].

OBJECTIVE: To investigate the evolution of left ventricular global strain in anterior myocardial infarction patients treated with emergency percutaneous coronary intervention (PCI).
 Methods: A total of 54 patients with PCI were enrolled as a PCI group. Forty healthy subjects were enrolled as a control group. Dynamic cardiac images were collected. All of these images were analyzed off-line by velocity vector imaging (VVI) software. N-terminal pro-B-type natriuretic peptide (NT-proBNP) was measured with an electrochemiluminescence immunoassay through the Elecsys 1010/2010 system. Correlation analysis were undertaken between VVI and NT-proBNP levels in blood.
 Results: In PCI group, only globle longitudinal strain (GLS) was significantly increased 3 day after operation (P<0.05). GLS and globle circumferencial strain (GCS) were markedly increased 6 months after operation (P<0.05). In PCI group, left ventricular GLS 1 d to 6 months after PCI shows positive correlation with lgNT-proBNP levels (r=0.66, P<0.001). GLS value was -12.50% at the 3rd day after operation, indicating the improvment of cardiac function in the first and sixth month after PCI.
 Conclusion: The change of Left ventricular globle longitudinal systolic function after emergency PCI may be more sensitive to the improvement of myocardial stunning after STEMI reperfusion; GLS value (-12.50%) at the 3rd day after operation predict the improvment of cardiac function in the first and sixth months after PCI.
