Clinical Characteristics, Mortality and Associated risk factors in COVID-19 patients reported in ten major hospitals of Khyber Pakhtunkhwa, Pakistan.

BACKGROUND: COVID-19 is an ongoing public health issue across the world. Several risk factors associated with mortality in COVID-19 have been reported. The present study aims to describe clinical and epidemiological characteristics and predictors of mortality in hospitalized patients from Khyber Pakhtunkhwa, a province in Pakistan with highest COVID-19 associated case fatality rate. METHODS: This multicentre, retrospective study was conducted in hospitalized COVID-19 patients who died or discharged alive until 1st May 2020. Data about sociodemographic characteristics, clinical and laboratory findings, treatment and outcome were obtained from hospital records and compared between survivors and non-survivors. Statistical tests were applied to determine the risk factors associated with mortality in hospitalized patients. RESULTS: Of the total 179 patients from the 10 designated hospitals, 127 (70.9%) were discharged alive while 52 (29.1%) died in the hospital. Overall, 109 (60.9%) patients had an underlying comorbidity with hypertension being the commonest. Multivariate logistics regression analysis showed significantly higher odds of in-hospital death from COVID-19 in patients with multiple morbidities (OR 3.2, 95% CI 1.1, 9.1, p-value=0.03), length of hospital stay (OR 0.8, 95% CI 0.7, 0.9, p-value <0.001), those presenting with dyspnoea (OR 4.0, 95% CI 1.1, 14.0, p-value=0.03) and oxygen saturation below 90 (OR 9.6, 95% CI: 3.1, 29.2, p-value <0.001). CONCLUSION: Comorbidity, oxygen saturation and dyspnoea on arrival and length of stay in hospital (late admission) are associated with COVID-19 mortality. The demographic, clinical and lab characteristics could potentially help clinician and policy makers before potential second wave in the country.

A case of peripartum cardiomyopathy presenting as bilateral acute limb ischaemia and gangrene.

Peripartum cardiomyopathy (PPCM) is a condition of unknown etiology that presents as heart failure due to left ventricular systolic dysfunction in the last of month of pregnancy and up to six months after giving birth. PPCM predisposes towards thrombo-embolism and an acute limb ischaemia can be a manifestation of this disease. We present a case of a 23-year-old lady presenting an acute lower limb ischaemia four months post-partum. Doppler ultrasound showed bilateral femoral emboli and cardiac ECHO showed a 24% ejection fraction. Amputation was performed on both limbs, below her right knee and above her left knee. The patient was started on heart failure medication and her symptoms improved with diuretic therapy, confirming the diagnoses of PPCM. It is important to recognise acute limb ischaemia as a rare manifestation of PPCM, as a timely diagnosis and effective treatment of the disease can improve the prognosis. We believe this is the first case to be reported in medical literature from Pakistan of a patient presenting PPCM with bilateral acute limb ischaemia and gangrene.

Radiation exposure in different cardiac catheterization procedures in cath lab.

BACKGROUND: Interventional procedures render cardiologolists and their team members to high doses of radiations. This study was conducted to assess the radiation exposure in various cardiac catheterization procedures. METHODS: This descriptive cross sectional study was conducted at the catheterization laboratory of Lady Reading Hospital Peshawar from November 2008 to December 2009. Patients were categorized into four groups for procedures a. coronary angiography, b. percutaneous coronary intervention (PCI), c. permanent pacemakers (PPM) and d. percutaneous transvenous mitral commisurotomy (PTMC), two groups for operators (consultants and trainees), and three groups for various accesses (femoral, radial and sub-clavian). RESULTS: A total of 99 patients undergoing cardiac catheterization were studied. Coronary angiography was performed in 52 (52.5%) patients, PCI in 32 (32.3%)), pacemakers in 6 (6.1%), and PTMC in 9 (9.1%) patients. Consultants did 72 (72.7%) procedures and trainees did 27 (27.3%) procedures. Through radial access, 22 (22.2%) procedures were performed, 71 (71.7%) through femoral, and 6 (6.1%) through sub-clavian. The mean radiation dose for coronary angiography was (4907.862 +/- 15231.6358 microGym2), PCI (10375.16 +/- 16083.4385 microGym2), pacemakers (1406.823 +/- 785.489 microGym2), and PTMC (1157.91 +/- 760.437 microGym2). The mean radiation dose for radial (6147.33 +/- 8480.37 microGym2), femoral (6512.58 +/- 16566.73 microGym2), and sub-clavian was (1406.82 +/- 785.48 microGym2). While for various operators consultants (7489.5 +/- 16925.55 microGym2), and trainees (2475.25 +/- 1178.86 microGym2). The mean time for radial (8.59 +/- 7.28 min), femoral (6.95 +/- 6.43 min) and sub-clavian was (8.24 +/- 4.81 min). The mean time for coronary angiography (4.56 +/- 5.32 min), PCI (11.44 +/- 6.92 min), PPM (8.24 +/- 4.81 min), and PTMC (8.28 +/- 5.01 min). CONCLUSIONS: Radiation dose varies substantially across different groups by different operators and different routes.

Comparative analysis of type of myocardial infarction in patients with successful or unsuccessful streptokinase thrombolysis following ST elevation myocardial infarction.

OBJECTIVE: To study the effect of thrombolytic therapy in term of success and failure on the type of ST elevation MI, using streptokinase. MATERIAL AND METHODS: This was a comparative study, conducted at Department of Cardiology, Lady Reading Hospital, Peshawar, from October 2006 to October 2007. Patients with first acute myocardial infarction were divided into group A (successful thrombolysis) and group B (unsuccessful thrombolysis) using ECG criteria. RESULTS: Total number of patients were 200. Group A included 136 (68%) patients and group B included 64 (32%) patients. There were total 88 (44%) patients of anterior MI with 47 patients in group A and 41 patients in group B (34.6% vs 64.0%, p < 0.001). There were total 110 (55.0%) patients of inferior MI with 88 patients in group A and 22 patients in group B (64.7% vs 34.4%, p < 0.001). Lateral myocardial infarction was diagnosed in 2 (1%) patients with 1 patient each in group A and group B (0.7% vs 1.6%, p = 0.583). CONCLUSION: Anterior MI was associated with a higher rate of thromblysis failure while inferior MI and lateral wall MI was associated with a higher rate of successful thrombolysis.
