Consumption of 1-2 eggs per day is not associated with an increased risk of cardiovascular disease, according to the following systematic reviews of studies:

Egg consumption in relation to risk of cardiovascular disease and diabetes: a systematic review and meta-analysis (AJCN, 2013):

This meta-analysis suggests that egg consumption is not associated
with the risk of CVD and cardiac mortality in the general population.
However, egg consumption may be associated with an increased incidence
of type 2 diabetes among the general population and CVD comorbidity
among diabetic patients.

Impact of Egg Consumption on Cardiovascular Risk Factors in Individuals with Type 2 Diabetes and at Risk for Developing Diabetes: A Systematic Review of Randomized Nutritional Intervention Studies (Canadian Journal of Diabetes, 2017):

Results from randomized controlled trials suggest that consumption of
6 to 12 eggs per week, in the context of a diet that is consistent
with guidelines on cardiovascular health promotion, has no adverse
effect on major CVD [cardiovascular] risk factors in individuals at risk for developing
diabetes or with type 2 diabetes. However, heterogeneities in study
design, population included and interventions prevent firm conclusions
from being drawn.

Egg Consumption and Human Cardio-Metabolic Health in People with and without Diabetes (Nutrients, 2015):

A high egg diet in the context of a background diet that is low in
saturated fats (a polyunsaturated to saturated fat ratio > 0.7), or a
diet that replaces saturated fats with poly- and mono-unsaturated
fats, is likely to result in positive or no adverse changes in LDL
cholesterol, and could be safely advised.

In some individuals, consumption of eggs, which are high in cholesterol, may increase LDL cholesterol levels and thus increase the risk of cardiovascular disease (Nutrients, 2015). In most individuals, high cholesterol intake is not associated with high blood cholesterol levels, though.

Dietary Cholesterol, Serum Lipids, and Heart Disease: Are Eggs Working for or Against You? (Nutrients, 2018):

Overall, recent intervention studies with eggs demonstrate that the
additional dietary cholesterol does not negatively affect serum
lipids, and in some cases, appears to improve lipoprotein particle
profiles and HDL functionality.
